✦ Synopsis

The product hydroxyl radical arising from the reaction 0( 1D 2)-t-H 2 ---, OH + H was detected by LIF following excitation of the off-diagonal transition OH(A2E +, v' = 1 6-X 2II, v" = 2) in the region 348-357 nm. The rotational population distribution in v" = 2 appears to be inverted and quite similar to that previously reported for v" = 0 and 1. Because rotationally cool OH was not observed,, there is no evidence for the existence of an abstractive pathway in which the subject reaction occurs without the initial formation, via insertion, of a chemically activated HOH collision complex.
