Normal Coordinate Analysis of Nitrogentrichloride S . N . RAI , BADRI RAI, K . P . R . NAIR, a n d S . N . THAKUR * Spectroscopy Laboratory, Department of Physics Banaras Hindu University, Varanasi-5, India (Z. Naturforsch. 27 a, 865—867 [1972] ; received 5 April 1972) The intramolecular force fields of nitrogen trichloride have been determined using the recent experimental data on the vibrational frequencies. Three different methods have been used for the evaluation of force constants. The results ob- tained are quite consistent. Introduction In a

C Y V I N Institute of Theoretical Chemistry, Technical University of Norway, Trondheim-NTH, Norway (Z. Naturforsdi. 2 6 a , 1346—1349 [1971]; received 22 April 1971) A complete normal coordinate analysis for the complex acetonitrile-boron trifluoride has been carried out for the first time. Mean amplitudes of vibration, Bastiansen-Morino linear shrinkages, and the most important Coriolis coupling constants have also been

Normal Coordinate Analysis of Some Hexahalide Anions of IV Group Elements M . N . A V A S T H I a n d M . L . M E H T A Department of Physics, University of Jodhpur, Jodhpur, India (Z. Naturforsdi. 26 a, 1137—1139 [1971] ; received 16 March 1971) The normal coordinate analysis has been applied to the hexachloride and hexabromide of tin, titanium, zirconium and hafnium, using the Urey-Bradley force field (UBFF) and orbital valence force field (OVFF) . It is observed that the stretching force constant increases as the oxidation number of the metal increases

Normal Coordinate Analysis and Mean Amplitudes of Vibration of Halate Ions Nitish K. Sanyal and L. Dixit Department of Physics, University of Garakhpur, Gorakhpur 273001, India (Z. Naturforsch. 29 a, 693 — 697 [1974] ; received April 2, 1973) A normal coordinate analysis of halate ions, viz. 35C103-, 37C103_, Br1603”, Br1803~ and 103~ has been carried out using a general valence force field and Wilson’s F —G matrix approach. Mean amplitudes of vibration for bonded halogen-oxygen and non-bonded oxygen-oxygen distances have been reported using Cyvin’s method
