Substituted Methanes. XV. Infrared Spectral Data, Assignments, and Calculated Thermodynamic Properties for Fluorotrichloromethane

Abstract

Infrared spectral data for gaseous CCl3F have been obtained in the region 400–3200 cm−1, using NaCl and KBr prisms. The present data are compared with previous Raman and infrared data, and assignments and calculated wave numbers are given. The fundamentals (*=liquid) are ν1(a1) 1085, ν2(a1) 534, ν3(a1) 351,* ν4(e) 846, ν5(e) 400,* and ν6(e) 245* cm−1. Thermodynamic properties were calculated for 17 temperatures from 100° to 1500°K and were compared with previous calorimetric results.
