The infrared spectra between 4000 and 10 cm−1 of t-butyl bromide-h9 and -d9 in the gas and liquid states, and the Raman spectra between 3500 and 10 cm−1 of the liquids under parallel and perpendicular polarizations, have been recordeds and assigned. The compatibility of the assignments for the light and heavy molecules has been checked by normal coordinate calculations, in which 14 valence force constants have reproduced 40 fundamental frequencies with an average error of 1.5%. The calculated thermodynamic properties of both molecules are presented for temperatures between 50 and 500 °K.

The far infrared (33–500 cm−1) spectra of a series of organotrichlorosilanes have been recorded. The Raman spectra (0–600 cm−1) have also been measured and the relative intensity and depolarization values of lines are tabulated. The spectra have been interpreted in detail and some low-frequency “group frequencies” are proposed for the SiCl3 moiety. The infrared (3200–33 cm−1) and Raman (0–3200 cm−1) spectra of α-chlorovinyltrichlorosilane have been recorded and a complete vibrational assignment is presented. Torsional oscillations of the SiCl3 group were observed for two of the molecules; barriers of 1.7 kcal/mole and 2.7 kcal/mole were calculated for the motion around the C—Si bonds of the vinyltrichlorosilane and the ethyltrichlorosilane molecules, respectively. The results are briefly discussed. Thermodynamic properties have been calculated for the latter two molecules.
