The Infrared Vibration-Rotation Absorption Bands of Methyl Cyanide and Methyl Fluoride

摘要

The study of the infrared absorption spectra of methyl cyanide vapor was undertaken primarily for determining the correct Coriolis coupling coefficient for the fundamental band. The study of some of the vibrationrotation fundamentals of the methyl fluoride molecule was undertaken primarily to investigate the effects of Coriolis resonance between the parallel band and the perpendicular band. Bands of both the isotopic species, CH3F and CD3F, were studied.
