 Title    Zur Kenntnis der Barium-und Strontiumhalogenidhydrate  
 Abstract    The following alkaline earth halide hydrates could be found by differential thermal analysis: The dehydration temperatures increase w ith the size of the anions and decrease with the radius of the cations. The dehydration of SrCl2 • H 20 gives rise to two DTA-peaks, but there is no half-hydrate formed according to high-tem perature IR-measurements. The X -ray data of SrJ2 . H zO are communicated.

 Title    Temperature Variation of Principal Moments of Some Polyatomic Crystals  
 Abstract    Principal moments of some of the polyatomic single crystals such as ammonium di-chromate, ammonium chromate, potassium chromate and potassium permanganate have been determined from room temperature down to liquid air temperature. These have been found to decrease with the decrease of temperature. This variation is smaller in magnitude. It has been observed that the tem perature coefficient of the principal moments has almost the same value over the entire range of temperature. This small variation of paramagnetism has been attributed to the variation of absorption frequency in solid state.

The pre­ pared compounds were characterized by chemical analysis, IR-spectra and X -ray diffraction methods (powder and single cystal). Some chemical properties are given. All results indicate that the new compounds are derivatives of the hitherto unknown ortho-molybdic (VI) and tungstic (Vl)-acids.

The magnetic moments and the epr-spectra of the complexes have been investigated. Some of the complexes show a tem perature dependent interaction between the radicalic nitroxyl groups of the ligands. By analysis of the epr-spectra in the solid state there was found in some cases an interaction between the metal ion and the unpaired electrons of the ligands.

 Title    Influence of Nucleic Acid Bases on the Light-induced Reduction of Methylene Blue: ESR and Optical Measurements  
 Abstract    The effect of the nucleic acid bases adenine, cytosine, thymine, uracil, and 5-bromo-uracil on the light-induced reduction of methylene blue in dimethylsulfoxide has been investigated by means of ESR and optical absorption studies. It could be shown that the nucleic acid bases act as electron acceptors. The experimentally obtained electron affinities are of the following order: cytosine > adenine > thymine » uracil and confirm, thus, the theoretical predictions.

 Title    Kinetics of Thermal Decomposition of Copper Soaps  
 Abstract    The thermal decomposition o f copper soaps has been studied both as a function of tempe­ rature and time. The whole range of the isothermal decomposition of copper soaps has been most adequately expressed by the P r o u t -T constants. In a previous communication 1 the decomposition of barium soaps was studied both as a function of temperature and time. In the present work a systemat­ ic study of the kinetics of the thermal decomposition of copper soaps has been undertaken and attemps have been made to test the validity of well known kinetic equations to account for the complete course of de­ composition.

The oscillation of the yellow Ce4+ ion s ca n be observed directly during the reaction. By silica-gel chromatography the brominated products of the reaction have been identified as dibromoacetic acid and bromomalonic acid.
