EFFECTS OF THE INTERMOLECULAR INTERACTION ON THE DEPOLARIZED ROTOTRANSLATIONAL RAMAN-SPECTRA OF HYDROGEN

Calculations of the rotational Raman spectra of hydrogen at high gas d ensities and various temperatures are presented. Both the far wings an d the line cores are considered where collisional induction and pressu re broadening shape the profiles. The treatment of far wings follows p revious calculations which had given encouraging results. In the prese nt work, new components of the collision-induced polarizability have b een considered in an attempt to remove the previously observed inconsi stencies with existing measurements. The far-wing spectral intensities and the Raman linewidths are computed by using two different intermol ecular potentials. It is shown that Raman linewidths are more sensitiv e to the details of the intermolecular potential than far-wing Raman i ntensities. Comparison with experimental data does not allow one to de termine which of the two potentials is to be preferred over the other.
