The harmonic force fields of BF 3, SnCl 4 SbBr 3 obtained by the joint use of electron diffraction and vibrational spectroscopy data

Abstract

The recently developed technique of joint analysis using electron diffraction and vibrational spectroscopy data for determining molecular force fields is demonstrated for the sample molecules BF 3 and SnCl 4. The technique is based on harmonic force constants being the common parameters in the interpretational methods of both components. The general harmonic force field of SbBr 3 is refined in this way using electron diffraction and recently available gas-phase spectroscopic frequencies of vibration.
