Abstract
Using Photocacoustic Spectroscopy and Fourier Transform Infra-lied Spectroscopy, the fundamental and overtone spectra of chlorotrifluoromethane up to the v=5 manifold was obtained. Rotational contour analysis of the C-F overtone bands and combination bands with C-C1 stretch yields new values for the harmonic frequencies and anharmonicity constants. Chlorotrifluoromethane has a greater normal mode character than local mode character due to the fact that the substitutent atoms are heavier than the central atom. The local mode analysis was carried out to extend the analysis to such extreme molecules. The local mode predictions are compared to the observed distribution of intensities among the 31 bands in the overtone region
