摘要：

Rate coefficients, in units of 10(-10) cm(3) molecule(-1) s(-1), for the O(D-1) reactions with H-2, D-2 and HD at 298 K were determined to be 1.2 +/- 0.1, 1.1 +/- 0.1, and 1.2 +/- 0.1, respectively. The H atom yield in the O(D-1) + HD reaction, relative to that in the O(D-1)+ H-2 reaction, was measured to be 0.57 +/- 0.03. The temporal profiles of O(P-3) and H(S-2), following pulsed photolytic generation of O(D-1), were measured using cw resonance fluorescence detection to determine the rate coefficients and product yield.
