Paper Abstract

The gas phase infrared spectra of specifically 1H-labelled propanes CHD2CD,CD, and CD3CHDCD3 together with the spectrum of CD3CD2CD3 have been measured between 11500 and 500 cm 1. Assignments of these spectra in the fundamental and overtone regions are proposed. The Raman spectra between 100 and 3000 cm-1 of the same compounds are also reported; they are necessary to give the full view of the vibrational spectrum at the fundamental level. The major spectral features of the overtone spectral region can be explained on the basis of coupling between overtones of C-H stretching vibrations and CHD deformation vibrations. Fermi resonance coupling interactions between the two types of overtones are stronger with increasing overtone number. The present results show that there is an effect on isolated C-H stretching frequencies due to deuterium substitution.
