 Title    Photoelektronen-Spektren und Moleküleigenschaften, 110 [1,2] Tricyanmethan-Derivate X—C(CN) 3 Photoelectron Spectra and Molecular Properties, 110 [1, 2] Tricyanomethane Derivatives X-C(CN) 3  
 Abstract    The photoelectron spectra of tricyanomethane derivatives X—C(CN) 3 with substituents X = H, CH 3 , Br and C 6 H 5 have been recorded and are assigned based on MNDO calculations as well as on radical cation state comparison with the iso(valence)electronic P(CN) 3 , within the series of cyanomethanes H 4 _"C(CN)", and with each other. For HC(CN) 3 , no traces of the isomeric dicyano, ketimine HN = C=C(CN) 2 are detected in the gas phase. Tricyanomethylbenzene, H 5 C 6 —C(CN) 3 , exhibiting the highest first ionization energy of any known singly acceptor substi-tuted phenyl derivative, demonstrates the tremendous electron withdrawing effect of the -C(CN) 3 group.

 Title    Synthesis and Photoelectron Spectroscopy of Spin Labeled Metal Complexes  
 Abstract    Two new spin labeled metal complexes; cobalt(II) bis(2,2,6,6-tetramethyl-l-oxyl-4-piperidyl p-salicylaldiminobenzoate) (3), copper(II) bis(2,2,6,6-tetramethyl-l-oxyl-4-piperidyl-p-salicyl-aldiminobenzoate) (4) were prepared. The synthesis of amino derivatives of nitroxide compounds were improved by a simplified synthetic route. The XPS spectra of 3 and 4 were determined. The observed N Is, Cu 2p and Co 2p spectra of spin labeled metal complex are discussed.

 Title    Röntgen-photoelektronenspektroskopische Untersuchungen an Pentacarbonyl- Chrom-und -Wolfram-Komplexen mit Stickstoffliganden c X-ray Photoelectron Studies of Pentacarbonyl Chromium and Tungsten Complexes with Nitrogen Ligands  
 Abstract    The ionization energies of some chromium and tungsten pentacarbonyl complexes of the type [M(CO)5] xL (L = N2H2, N2H4, NH3; x = 1 or 2 for N2H4 or a; = 1 for N2H2) are reported. The results are discussed in terms of the effects of tr-donor and 7r-acceptor bonds on XPS data. Satellite lines, which can be explained in terms of a shake-up process, give information about the nature of the metal-ligand bond. These shake-up processes are, to a large extent, specific to the atoms of the acceptor groups. The spectroscopic and chemical importance of multi-peak structures of XPS bands is emphasised.

 Title    Photoelectron Spectra of Dithiapropellanes  
 Abstract    The photoelectron spectra of the dithiapropel-lanes 1 to 5 have been recorded. The first bands have been assigned by comparison with the PE spectra of cyclic thioethers. The resonance inte-gral between the 3p orbitals of the sulfur centers in 1 to 5 is found to be —0.15 to —0.25 eV.

 Title    The Electronic Structure and the He(I) Photoelectron Spectrum of Tricarbonylcyclooctatetraene-iron [1]  
 Abstract    The highest occupied molecular orbitals of tricarbonylcyclooctatetraene-iron (1) have been derived from those of tricarbonyl-butadiene-iron and butadiene. Based on this MO diagram and an INDO-type calculation the He(I) photoelectron (PE) spectrum of 1 could be interpreted. Using the A SCF and the transition operator method (TOM) the first five bands of the PE spectrum of 1 could be assigned.

 Title    Gasphasen-Reaktionen, 35 [1] Benzseleniren als kurzlebiges Zwischenprodukt in der Pyrolyse von 1.2.3-Benzoselenodiazol zu 6-Fulvenselon Benzselenirene as Short-lived Intermediate in the Pyrolysis of 1,2,3-Benzoselenodiazole to 6-Fulvenselone  
 Abstract    In the pyrolysis of 1,2,3-benzoselenodiazole using a short-distance furnace, a short-lived intermediate is detected photoelectron spectroscopically. Mass spectra recorded under similar conditions suggest an isomer CöHiSe rearranging to the more stable final product 6-fulveneselone. The ionization pattern obtained by computerized spectra stripping is assigned to benzselenirene by molecular radical cation state comparison based on MNDO calculations.

 Title    Photoelectron Spectra and Molecular Properties, LXIX [1,2] Molecules with S—N Multiple Bonds  
 Abstract    The He(I) photoelectron spectra of the following molecules with S—N multiple bonds S=N /-N. 4 ,h O R=CH3/CF3/Ct n = 2,3 are assigned by radical cation state comparison between the chemically related compounds as well as by MO models based on CNDO calculations. From the ionisation energies of the 0 = S = 0/HN = S = 0 pair a parameter OSN can be deduced, which proves to be useful in the discussion of other SN compounds like R3C-N=S = 0 and RN = S = NR.

 Abstract    The photoelectron (P E) spectra of bis(dialkylam ino) acetylenes R 2N — C = C —N R 2 and o f tet-rakis(dialkylam ino) allenes (R 2N)2C = C = C (N R 2)i with R = C H 3, C2H 5 exhibit characteristic ionization patterns which are assigned to re radical cation states of the two m olecular halves twisted against each other. The low first ionization potentials betw een 7.0 eV and 7.7 eV stim u­ lated attempts to oxidize using A1C13 in H 2CC12 or D 2CC12. The hyperfine structured E SR spectra observed can be unequivocally assigned to the ethylene radical cations R 2N — HC = CH — N R 2 © which are formed from the obviously non-persistent species R2N —C ^ C — N R 2 ® via a hydrogen transfer. During the oxidation o f the dialkylam ino-substituted allenes no paramagnetic interm edi­ ates could be d etected , presumably due to a rapid dimerisation o f the allene radical cation (R 2N)2C = C = C (N R 2)2'®.

 Title    Gasphasen-Reaktionen, 59 [1, 2] Die Pyrolysen von Trifluormethylazid und Hexafluorazomethan Gas Phase Reactions, 59 [1, 2] The Pyrolyses of Trifluoromethylazide and Hexafluoroazomethane  
 Abstract    Trifluoromethyl azide decomposes in a low-pressure flow system at rather high temperatures by splitting off N 2 . The nature of the resulting products depends largely on the wall material of the pyrolysis tube: using molybdenum above 1120 K, FCN is observed exclusively. Neither F 2 C=NF nor F 3 C—N=N—CF 3 can be detected as intermediates by comparing their PE spectra with those continuously recorded while increasing the temperature. F 3 C—N = N — CF 3 fragments already at 870 K to give N 2 and F 3 C-CF 3 . The PE spectra of F 3 CN 3 and F 2 C=NF are assigned based on MNDO calculations.
