✦ Synopsis

Abstract

Measurements of the width of the rotational Raman line, at 595 cm^−1^, of hydrogen in mixtures with N~2~, C~2~H~4~ and CO~2~ are reported at a series of perturbing gas pressures, up to 400 bar. The broadening is found to be characteristic of the foreign gas and is interpreted in term of the quadrupole–quadrupole interaction between hydrogen and the perturing molecule. It is shown that the quadrupole–quadrupole contribution is the dominant part of the anisotropic intermolecular potential.
