H2-Ar intermolecular potential from the spectrum of the complex and the Raman linewidths

Abstract
The ability of some intermolecular potential models to describe both the Raman linewidths of the H2 molecule perturbed by Ar and the fine structure of the infrared spectrum of the van der Waals complex H2-Ar is examined. It can be concluded that, due to the experimental uncertainties, none of the investigated potential models leads to a significantly better value of the mean square deviation between theoretical results and experimental data, than any of the others.
