The H2S Raman spectrum in the range 40-450 cm-1 at room temperature and 1.5 bar has been measured and analyzed. The frequency dependence of both the optical anisotropy δ2 and the ratio Rγβ = γ β are studied. The variation of the nuclear configuration, due to centrifugal distortions, is found to affect more significantly δ2 than Rγβ. Absolute Raman cross sections are obtained by using a method different from the previously adopted one. The derived principal polarizabilities are compared with other experimental and theoretical data available in the literature. © 1986.
