Abstract
The infrared‐absorption spectra of liquid phenyltrichlorosilane, phenyltrichlorogermane, and phenyltrichlorostannane have been recorded from 4000 to 33 cm−1. The Raman spectra of the liquids have also been recorded and depolarization values have been measured. The phenyl vibrations have been assigned assuming C2v symmetry, although the molecular symmetry is probably Cs. All the spectra are interpreted in detail, and the 39 fundamental vibrations have been assigned based on previous assignments for substituted benzenes as well as the expected band positions and depolarization values. Comparison of the spectra reported herein to that of the carbon analog suggests the reassignment of a few of the fundamental vibrations in phenyltrichloromethane. The assignment of the lowest observed Raman line in each spectrum to the torsional vibration is discussed, but because of the large values calculated for the sixfold barrier hindering internal rotation it is discarded.
