✦ Synopsis

A study of vibrational energy transfer for four aromatics with the collision partners H, and He has been undertaken to assess the role of V + R transfer when a low moment of inertia collision partner is involved. Significant transfer occurs to 0' (the only channel for which V + R transfer can occur) in relaxation of benzene and benzene-d, by Hz, but not by He.

For both p-difluorobenzene and toluene there is significant transfer to 0' by both He and Hz, preventing the observation of V -+ R transfer in these polyatomics. It is found that He adopts different pathways when heavy groups are attached to the ring. Hz is more consistent in its preferences.
