Calculated isotropic Raman spectra from interacting H sub(2) rare-gas pairs

We report on a theoretical study of the H sub(2)-He and H sub(2)-Ar pair trace-polarizability and the corresponding isotropic Raman spectra. The conventional quantum mechanical approach for calculations of interaction-induced spectra, which is based on an isotropic interaction potential, is employed...

description	We report on a theoretical study of the H sub(2)-He and H sub(2)-Ar pair trace-polarizability and the corresponding isotropic Raman spectra. The conventional quantum mechanical approach for calculations of interaction-induced spectra, which is based on an isotropic interaction potential, is employed. This is compared with a close-coupling approach, which allows for inclusion of the full, anisotropic potential. It is established that the anisotropy of the potential plays a minor role for these spectra. The computed isotropic collision-induced Raman intensity, which is due to dissimilar pairs in H sub(2)-He and H sub(2)-Ar gas mixtures, is comparable to the intensities due to similar pairs (H sub(2)-H sub(2), He-He, and Ar-Ar), which have been studied previously.
