Abstract
Rovibrational Raman spectra of low density H2S gas have been measured with the aim of extracting the components of the polarizability tensor derivatives with respect to the normal modes of the molecule. Absolute values are obtained by comparison with the intensity of the symmetric stretching polarized Q-branch available in the literature. A fit to the free rovibrational spectra is employed in order to separate overlapping bands and to determine the anisotropy ratio for the totally symmetric A 1 bands. The results are compared with those obtained with a bond polarizability model and with SCF calculation performed by Martin, Davidson and Eggers [5].Keywords
