Substituted Methanes. XIV. Vibrational Spectra, Potential Constants, and Calculated Thermodynamic Properties of Bromochloromethane

Abstract

Raman displacements, semiquantitative relative intensities, quantitative depolarization factors, and wave numbers for the infrared bands in the region 400–3000 cm⁻¹ have been obtained for CH₂BrCl. A reasonable set of potential constants has been determined using Wilson's FG matrix method. The thermodynamic properties—heat content, free energy, entropy, and heat capacity—have been calculated from the spectroscopic and molecular structure data for 11 temperatures from 100 to 1000°K.
