 Title    New Mechanism for Facile Charge Transport in Polypeptides  
 Abstract    An electronic hole migration accross a polypeptide chain is discussed with special reference to new ab initio computational results and to the experimental observations of Weinkauf et al. on the charge photoinjection into the polypeptide backbone. New mechanistic details for this efficient charge transport process are proposed. The process is viewed as a vibronically induced hole hopping between local aminoacid sites driven by large amplitude torsional motions of the floppy backbone.

 Title    Heat Capacity of the Rb 3 LnCl 6 Compounds with Ln = La, Ce, Pr, Nd  
 Abstract    The heat capacities of the solid and liquid Rb 3 LnCl 6 compounds, where Ln = La, Ce, Pr, Nd, have been determined by differential scanning calorimetry (DSC) in the temperature range 300 -1100 K. The heat capacity shows a small decrease with increasing temperature from the temperature of phase transition up to 150 -200 K above this transition for the Rb 3 CeCl 6 , Rb 3 PrCl 6 and Rb 3 NdCl 6 compounds. The measured heat capacities were used to calculate the formation enthalpy of the liquid phase. The results obtained compare satisfactorily with the known experimental data.

 Title    Local Correlation's Potential for Noise Reduction and Symbolic Partitions  
 Abstract    We investigate local correlation dimension-based noise-cleaning of time series, where points having anomalously large dimensions are iteratively removed from the reconstructed attractor. We find an optimal range for the number of iterations in which the algorithm yields good results. Choosing non-local ranges for the linear regression yields a new method for finding nonhyperbolic tangency points. The method is also applicable for noisy systems with unknown dynamics; in this case, noise facilitates the detection of the points.

 Title    The Effects of Collisions with Neutral Particles on the Instability of Two Superposed Composite Plasmas Streaming Through Porous Medium  
 Abstract    The effects of collisions with neutral atoms on the hydromagnetic stability of the plane interface separating two streaming superposed composite plasmas of uniform densities in a porous medium are investigated. In the absence of fluid velocities, it is found, for a potentially stable configuration, that the system remains stable, while for a potentially unstable configuraion, the unstable system becomes stable under a certain condition of the wavenumber depending on the values of the fluid densities, Alfven velocities, and the orientation of the magnetic field. The porosity of the porous medium does not have any significant effect on the stability criterion. In the presence of fluid velocities, it is found that, the instability criterion is independent of the permeability of the medium and the collision effects with neutral particles. The criterion determing the stability does not depend on the permeability of the medium but depends on the density of neutral particles. The porosity of the medium is found to have a significant effect on both the stability and instability criteria in this case. The role of the permeability of the medium, the collisional frequency, and the porosity of the porous medium on the growth rate of the unstable mode is examined analitically. Routh's test of stability is applied to confirm the above results.

 Title    Dynamic Solvent Effects in the Degenerate Isomerization of a Hexafluoroacetone Anil Studied by High-Pressure 19 F NMR  
 Abstract    The rate of the degenerate isomerization of A^-hexafluoroisopropylidene-V,V-dimethyl-/?-phe-nylenediamine was measured by high-pressure 19 F NMR spectroscopy in a viscous hydrocar-bon, 2,4-dicyclohexyl-2-methylpentane. Pressure-induced retardations that cannot be rationalized within the framework of the transition state theory (TST) were observed, and it was concluded that the reaction was cast into the TST-invalid nonequilibrium conditions by high pressure.

 Title    Nuclear Quadrupole Interactions in Cadmium Complexes: Semiempirical and ab initio Calculations  
 Abstract    Semiempirical calculations, based on the so-called angular overlap model, have been compared with ab initio methods (MP2) for the calculation of nuclear quadrupole interactions (NQPs) in cadmium complexes with biologically relevant ligands (H2O, OH -, cysteinate, carboxylate, and imidazole). The assumptions on which the semiempirical model is based have been tested and the comparison indicates that: 1) A change in the Cd-ligand bond length by 0.1 A may change the electric field gradient (EFG) by about 0.2 a. u.. A simple scheme to incorporate such effects in the semiempirical method is suggested. 2) The effect of ligand-ligand interactions is up to about 0.2 a. u. for the largest diagonal element of the EFG tensor for the tested complexes, and such effects can significantly influence the so-called asymmetry parameter. 3) The position of non-coordinating atoms on the ligands can in some cases (e. g. the hydrogen atoms of water) significantly influence the EFG. The combined effect of non-coordinating atoms and ligand-ligand interactions may cause deviations of up to 0.35 a.u. between ab initio and the semiempirical calculations. 4) In the semiempirical model each ligand is characterised by one parameter, the so-called partial nuclear quadrupole interaction. This parameter has been evaluated by ab initio calculations, and agreement was found within about 0.2 a. u. (« 40 Mrad/s) for all ligands except imidazole. 5) A change in the coordination number from 2 to 6 may change the partial NQI by about 0.3 a. u.

 Title    NMR Studies on Dynamics of Water Intercalated in Clay Minerals  
 Abstract    The dynamics of water molecules intercalated in D2O saturated synthetic and natural smectites, and a synthetic Na-fluormica were studied by measurements of solid state 2 H NMR spectra and spin-lattice relaxation times at 150 — 370 K. The obtained results could be explained by the 2-site flip, the C2 rotation and the isotropic rotation of the D2O molecules in smectites. In fluormica, the isotropic motion was undetectable, but the axial rotation of the hydration sphere as a whole was observed. The activation energies and correlation times of the C2 rotation were almost independent of the interlayer cations but depended on the character of clay-layers.

 Title    Hydrogen Bonds in Crystalline Imidazoles Studied by 15 N NMR and ab initio MO Calculations  
 Abstract    Intermolecular hydrogen bonds of the type N-H...N in crystals of imidazole and its 4-substituted and 4,5-disubstituted derivatives were studied by 15 N CP/MAS NMR and an ab initio molecular orbital (MO) calculation. In the 15 N CP/MAS NMR spectrum of each of the imidazole derivatives, two peaks due to the two different functional groups, >NH and =N-, were observed. The value of the I 5 N isotrop-ic chemical shift for each nitrogen atom depends on both the length of the intermolecular hydrogen bond and the kind of the substituent or substituents. It was found that the difference between the experimen-tal chemical shifts of >NH and =N-varies predominantly with the hydrogen bond length but does not show any systematic dependence on the kind of substituent. The ab initio MO calculations suggest that the hydrogen bond formation influences the 15 N isotropic chemical shift predominantly, and that the difference between the 15 N isotropic chemical shift of >NH and =N-varies linearly with the hydrogen bond length.

 Title    Pulse Power Compression by Cutting a Dense Z-Pinch with a Laser Beam  
 Abstract    A thin cut made through a z-pinch by an intense laser beam can become a magnetically insulated diode crossed by an intense ion beam. For larger cuts, the gap is crossed by an intense relativistic elec-tron beam, stopped by magnetic bremsstrahlung resulting in a pointlike intense x-ray source. In either case, the impedance of the pinch discharge is increased, with the power delivered rising in the same pro-portion. A magnetically insulated cut is advantageous for three reasons: First, with the ion current com-parable to the Alfven ion current, the pinch instabilities are reduced. Second, with the energy deposit-ed into fast ions, a non-Maxwellian velocity distribution is established increasing the (crv) value for nuclear fusion reactions taking place in the pinch discharge. Third, in a high density z-pinch plasma, the intense ion beam can launch a thermonuclear detonation wave propagating along the pinch discharge channel. For larger cuts the soft x-rays produced by magnetic bremsstrahlung can be used to drive a thermonuclear hohlraum target. Finally, the proposed pulse power compression scheme permits to use a cheap low power d.c. source charging a magnetic storage coil delivering the magnetically stored en-ergy to the pinch discharge load by an exploding wire opening switch.

 Title    The Physical and Molecular Properties of New Low Melting Nematics with Negative Dielectric Anisotropy  
 Abstract    The paper presents some basic physical properties (static electric permittivities, refraction indices, density and viscosity) of 2-chloro-4-n'-alkylphenyl esters of 4-/r-alkylbicyclo[2,2,2] octane-1-carbox-ylic acids (n'=l, n = 5 and 7) which are, at room temperature, nematics with a negative dielectric an-isotropy. On the basis of temperature dependence of the principal static permittivities £ H (T) and e±(T) of the nematics, using the Maier-Meier equations, the angle between the dipole moment vector and the long axis of mesogenic molecules, the apparent molecular dipole moment square pl P[) {T), and the ne-matic order parameter S(T) were determined.

 Title    Darkness Intensified -Existence of a Nonlinear Threshold in Redshift-Induced Dimming  
 Abstract    Redshift obeys adiabatic invariance. From this fact it follows that not only the individual photons are dimmed by a factor of z + 1 (if z is the redshift in percent), but the photon flux is re-duced by the same factor once more. Hence the luminosity of any source is in the presence of redshift dimmed by a factor of (z+1) 2 . This model-independent result possibly "explains away" the excess dimming of strongly redshifted Type-la super-novae, discovered in 1998.

 Title    High Pressure Dielectric Studies of a Substance with the Smectic A 1 Phase  
 Abstract    The results of dielectric studies of 5-n-hexyl-2-(4'-isothiocyanato)-l,3-dioxane (6DBT) in the smec-tic A, phase at pressures up to 150 MPa and temperatures up to 340 K are presented. The low frequen-cy relaxation time T\\ (/?, T) yields the activation volume A # V|| = RT(d ln Tjj/9/>) r and activation enthal-py A # //jj = R(d ln T||/37) p . The calculated values of these parameters are compared with those ob-tained recently for n-octyl-cyanobiphenyl (8CB) forming the smectic A d phase. In the case of 6DBT both these quantities are practically constant, whereas those for 8CB decrease, when going away from the phase transitions isotropic -smectic A] (6DBT) or nematic -smectic A d (8CB). These differences support our earlier conclusion that increase of pressure leads to a breaking of the antiparallel associa-tions of cyanobiphenyl molecules in the smectic as well as in the nematic phases.

 Title    Laser Ignition of an Isentropically Compressed Dense Z-Pinch  
 Abstract    A dense z-pinch generated by a high voltage discharge over a corrugated helical sawtooth-shaped cap-illary tube with a solid DT core, is by shear flow stabilized against the m = 0 and m= 1 magnetohydro-dynamic instabilities, and by rotational flow against the Rayleigh-Taylor instability. The shear-and rota-tional flow result from jet formation by the corrugated surface. A programmed voltage pulse can then isentropically compress the DT core to high densities, and if ignited at one end by a petawatt laser pulse, a thermonuclear detonation wave can be launched propagating along the z-pinch channel. The proposed z-pinch burn should also work without tritium as a thermonuclear detonation wave in deuterium.

 Title    Investigations on a Universal Relationship Between Optical Emission and Absorption of Complex Molecules in Liquid Solutions  
 Abstract    Based on a universal relationship between the extinction coefficient and the fluorescence intensity in their overlapping region, local temperatures T* higher than the ambient T were determined for short-lived luminescent molecules of lifetimes from 7 ps to 77 ps. The reason for such a local temperature T*, which holds also during the emission process, is the non-establishment of statistical equilibrium over the vibrational levels of excited molecules. It is found that the intensity distribution in the fluorescence band depends slightly on the wavelength of the excitating light, which evidences the lack of thermal equilibrium with the vicinal surrounding.

 Title    Electrohydrodynamic Interfacial Stability Conditions in the Presence of Heat and Mass Transfer and Oblique Electric Fields  
 Abstract    A novel mathematical formulation to deal with interfacial stability problems of the Kelvin-Helmholtz type with heat and mass transfer in the presence of oblique electric fields is presented. The perturbed system is composed of two homogeneous, inviscid, incompressible, dielectric, and streaming fluids sep-arated by a horizontal interface, and bounded by two rigid planes. The effect of a phase transition on the instability is considered, and the linear dispersion relations are obtained and discussed. It is found that the electric field has a major effect and can be chosen to stabilize or destabilize the flow. For Ray-leigh-Taylor instability problems of a liquid-vapor system it is found that the effect of mass and heat transfer enhances the stability of the system when the vapor is hotter than the liquid, although the clas-sical stability criterion is still valid. For Kelvin-Helmholtz instability problems, however, the classical stability criterion is found to be substantially modified due to the effects of the electric field, mass and heat transfer. A new stability condition relating the magnitude and orientation of the electric field and the dielectric constants is obtained. Oblique electric fields are found to have stabilizing effects which are reduced by the normal components of the electric fields. The effects of orientation of the electric fields and fluid depths on the stability configuration are also discussed.

 Title    Structure and Vibrational Spectra of the Vapour Molecules Fe 2 Cl 6 and AlFeCl 6  
 Abstract    Melting of aluminium and iron trichloride crystals is accompanied by a structural transition from octa-hedral to tetrahedral coordination of the metal ions, and a widely accepted interpretation of their liquid structure is that it mainly consists of strongly correlated dimeric units. Such A1 2 C1 6 and Fe 2 Cl 6 mole-cules are stable in the vapour phase and coexist in gaseous mixtures together with AlFeCl 6 molecules. In this work we extend to Fe 2 Cl 6 and AlFeCl 6 our earlier study of the ionic interactions in A1 2 C1 6], using a model which accounts for ionic deformability through (i) effective valences and (ii) electrostatic and overlap polarizabilities. The main disposable parameters of the model are adjusted to the Fe-Cl bond length in FeCl 3 monomer molecule and to the Fe-Fe bond length and a bond-stretching frequency in the Fe 2 Cl 6 molecule. The results are used to evaluate the structure of the AlFeCl 6 molecule, which has so far only been inferred from the observed Raman spectrum in mixed vapours. Extensive comparisons with data on molecular vibration-al frequencies are also presented for Fe 2 Cl 6 and AlFeCl 6 .

 Title    A Contribution to the Study of Ternary Saturated Electrolyte Solutions  
 Abstract    A quantity has been introduced, whose dependence on the composition along the branches of the sol-ubility isotherms of ternary systems consisting of two salts with a common ion and water exhibits breaks, which can be explained by the introduction of a previously unobserved configuration of the ternary sat-urated solution. In the respective region, a saturated solution in a ternary system may undergo second-order phase transitions to achieve specific configurations that are not derived from the structure of the binary saturated solution of the particular solute. It is assumed that further study of this phenomenon could contribute to a better understanding of the processes occurring in concentrated electrolyte solu-tions.

 Title    Molecular Motion in Tetraphenyltin Studied by NMR  
 Abstract    NMR second moment and spin-lattice relaxation times in the laboratory (60 and 25 MHz) and in the rotating frame (B { = 2.1 mT) were studied for polycrystalline tetraphenyltin Sn(C 6 H 5) 4 in a wide tem-perature range. Two kinds of motions were detected: isotropic rotation of whole molecules and reorien-tations/oscillations of phenyl rings. A dependence of the potential energy of the molecule in the crystal on the angle of the phenyl ring rotation about the Sn-C bond was obtained on the basis of atom-atom calculations. The amplitude of the ring-oscillations at 133 K was estimated as ± 7°. Below room tem-perature the magnetisation recovery is significantly non-exponential, which may be interpreted as due to the correlated motion of phenyl rings.

 Title    Steady-state and Time-resolved Spectroscopic Studies of Benzanilides  
 Abstract    Steady-state and time-resolved spectroscopic studies of benzanilide (I) and jV-methylbenzanilide (II) were performed at 298 and 77 K in various solvents. The results indicate that benzanilide fluorescence in non-polar solvents at room temperature involves three independent modes of emission: F! (LE) nor-mal fluorescence from the initially excited state Sj (LE) with ^^=320 nm, F^PT) fluorescence from the proton transfer tautomer with ^^=468 nm, F^CT) fluorescence from the species where intramo-lecular charge transfer appears, with ^^=510 nm. At 77 K in MCH a new fluorescence band, F ag , appears at Am ax = 4 15 nm instead of the F 2 (PT) and F^CT) fluorescence. This new emission originates from benzanilide dipolar aggregates or cis-imidol dimers. The decay times of these emission modes are different. yV-methylbenzanilide, dissolved in nonpopular and weakly polar solvents at room temperature and at 77 K, shows only two fluorescence modes, i.e., the normal and the charge-transfer emissions at 320 nm and 520 nm, respectively. The fluorescence is deactivated with two decay times, 30 ps and 2.05 ns, in MCH solution.
