Abstract
Experiments are reported showing that collisional V-V transfer between the ν6 (inplane wag, 989-cm-1) and ν4) (out-of-plane bend, 938-cm-1) vibrational modes is remarkably rapid, occurring with approximately gas-kinetic efficiency. Earlier studies of D2CO/D2CO collisions have been extended to a variety of collision partners (He, Ar, CH4, N2, N2O), providing some control of the relative rates of ν6 → ν4 transfer and of rotational relaxation with respect to quantum numbers J and Ka. The extraordinary efficiency of collision-induced ν6 → ν4 transfer in D2CO is attributable to the rovibrational mixing effect of Coriolis coupling and the availability of a number of efficient quasielastic relaxation channels.
