Abstract : The Raman spectra of solid CO2, N2O, N2, and CO have been observed. Each spectrum can be analyzed by assuming an approximately ordered structure isomorphous with that of CO2. The lattice mode intensities have been calculated on the basis of the oriented gas model; they are in good agreement with the measured values, and lead to confident assignments of the observed bands. The peak frequencies of these bands decrease an average of 15% on warming from 15K to the phase transition and there is a considerable concommitant increase in their widths. (Author)
