Vibrational Spectrum of CF3CN

Abstract

The Raman spectrum of liquid CF₃CN has been obtained at −100°C. The infrared spectrum of the gas at room temperature has been obtained from 2 to 38μ. The analysis of these data yield the fundamentals, which are used to interpret the overtone and combination bands. A qualitative discussion of the character of the vibrations, which is based upon comparison with other molecules of the CF₃X type, is given in terms of orthogonal characteristic vibrations. The results of a normal coordinate analysis are included.
