The effect of diatom-diatom collisions on depolarized light scattering linewidths

As an application of the general theory given in the previous paper1), distorted wave Born approximation calculations on the depolarized linewidths for H2 and D2 systems are presented. An assumed square well model for the spherical potential and dominant P2 and quadrupole-quadrupole nonspherical interactions are used to analyze the temperature dependence of both DPR and rotational Raman linewidths. Comparison with the excellent experimental results of van den Hout and coworkers2,3 is made and satisfactory agreement is found.
