Vibrorotational Raman and infrared spectra of polar diatomic molecules in inert solutions. III. Isotropic and anisotropic Raman spectra of HCl in liquid SF6

摘要

The isotropic and anisotropic Raman spectra of HCl diluted in liquid SF6 have been analyzed and compared with available experimental data. The theoretical profiles have been calculated with a non-Markovian spectral theory in which the statistical parameters of the isotropic and the anisotropic interaction were obtained from a microscopic extended cell model for the liquid. Memory and interference effects are qualitatively and quantitatively analyzed in terms of the time scales involved in the Raman spectra. A detailed study of intrabranch, interbranch, and cancellation mixing effects is carried out together with the analysis of the contribution of the different relaxation channels.
