Substituted Methanes. II. Vibrational Spectra and Calculated Thermodynamic Properties of Deuterotribromomethane

Abstract

Raman displacements, semiquantitative relative intensities, quantitative depolarization factors, and wave numbers and percent transmission for the infra-red bands in the region 400–5000 cm−1 have been obtained for CBr3D. Details about the measurement of the depolarization factors are given. Thermodynamic properties—heat content, free energy, heat capacity, and entropy—have been calculated from the spectroscopic and molecular structure data for eight temperatures from 298.16° to 1000°K.
