The energy disu-ibulion or nascent OH('n. v. J) produced in the reaclien o. r O('D) wilh H,S has been measured by leser-lnduccd fluorescence.

The rate constant for the reaction between OH and vibrationally excited H2, OH + H 2 (v = 1) ~ H20 + H, has been measured directly at 298 K. kol is found to be (7.5 -+ 3) X 10 -13 cma/molecule s, corresponding to a vibrational rate enhancement ofkol/koo = (1.2 -+ 0.4) X 102.
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 simi
