Raman and Infrared Spectra of Matrix Isolated CO2and CS2

Abstract
The matrix isolation infrared and Raman spectra of CO2 and CS2 in solid krypton at 20°K are reported. The fundamental frequencies are only very slightly red-shifted from the free gas values. Isotopic effects are found in both infrared and Raman spectra, whereas site splittings are evident in the infrared only.
