✦ Synopsis
The cherniluminescence in the H+ 0, -OH(X *lIIW,& +O, reaction was observed uvng a crossed beam tcebnlqu& l%e tnilial population of the OH radicals tn the vibratIonal slate v (4 < u UG 9) were found to be N( 9) -1.0, N(B) -0.95&O 1, N(7) -0.9kO.2, N(6) -0 2*0 1 and N(5) -N(4) -0 2&O 2 The IOEII crow, section of the formation of 0H(4 ( u < 9) wz estimnlcd to be 01 the order 01 10e2 nm'. No chenulummexence war observed in the reaction D + 0, + OD(X 2 ll,,r,/2)+ O1 under the prcsurt expenmcntal condrtiona.
