Abstract

State-to-state branching ratios are reported for vibrational energy transfer in benzene and benzene-d₆ due to collisions with D₂ and with He in a supersonic free jet expansion. In both the benzene and benzene-d₆ experiments the initial vibrational level pumped was 6¹. The state-to-state branching ratios are different for D₂ compared with He in C₆H₆ and in C₆D₆. In particular, there is a significant increase in transfer to the 0⁰ level for D₂ compared with He. It is postulated that this may be due to the small moment of inertia of D₂, which makes V→R transfer an important mechanism for this collision partner.
