Abstract
Wave numbers and estimated relative intensities for the infrared absorption bands of CCl3H, CCl4, and CCl3Br and a percent transmission curve for CCl3Br in the region 400–3500 cm−1 are given. Probable values of the infrared wave numbers are established and compared with previously obtained Raman and calculated values. Assignments of the observed bands are made. Thermodynamic properties—heat content, free energy, entropy, and heat capacity—have been calculated from the spectroscopic and molecular structure data to a rigid rotator, harmonic oscillator approximation for nine temperatures from 298.16° and 1000°K.Keywords
