Abstract
The Raman spectrum of neopentane is measured in the regions of ΔvCH=1 and 2. The results are compared to the absorption spectrum of neopentane in the region from ΔvCH=2 to 5. The peak positions are calculated within the local mode model. The intensity patterns observed in both types of spectra are explained. In particular, electrical anharmonicity is found to make a significant contribution to the observed peak intensities.Keywords
