Abstract
The vapour phase Raman spectra of the molecules F12CH3, F13CH3, H12CCl3, and H13CCl3 have been recorded at pressures of ca. 1 atmosphere over the fundamental frequency regions. Partly resolved rotational structure is reported for some fundamentals of methyl fluoride. The Raman band contours of the e-species fundamentals have been analysed to yield Coriolis constants from which e-species force constants have been calculated. The Coriolis and force constants so determined are compared with those based on analyses of appropriate vapour phase infra-red spectra.Keywords
