Absolute rate constants for the reaction OD + DNOJ have been determined at 297 + 2 K, using a pulsed laser photolysis-resonance absorption technique. The values (in cm3 mol-' s-l) obtained for DN03 alone and in the presence of 107 Torr SF, and at + 3a are (5.47 zb 0.75) x lo9 and (8.51+ 0.72) x lo9

Relative rate measurements of the reactions of the HO-radical with CO [HO + CO -+ H + COa (1) ] and with isobutane [HO f iso-C4H10 -t Hz0 f f-(or iso-)CaHg ( 3)J have been made through the photolysis of dilute mixtures of HONO with CO, ixo-Cd H ro, N0a, and NO in simulated air at 700 and 100 torr pr
The effect of pressure on the rate constant of the OH + CO reaction has been measured for Ar, N,, and SF, over the pressure range 200-730 torr. All experiments were at room temperature. The method involved laser-induced fluorescence to measure steady-state OH concentrations in the 184.9 nm photolysi
