✦ Synopsis
The polarized rovibrational Raman spectra of the v1 band of hydrogen sulphide in the gaseous phase, at a pressure of 2 atm, were recorded in order to redetermine the relative components of the polarizability tensor derivative associated with the Q, normal coordinate of this molecule. For the computation of the rovibrational levels entering the simulation of the depolarized spectrum, a Watson's A-reduced hamiltonian was used. A determination of the Rbm ratio of the components of the tensor more accurate than that of previous workers was possible. The results are discussed and compared with the bond polarizability theory predictions.
