Direct determination of the rate coefficient for the reaction of O(D-1) with OCS
A gaseous mixture of O-3/OCS/He was irradiated at 266 nm with a pulsed laser, and vibrationally excited SO(X-3 Sigma , v = 8 and 19) generated in the reaction of O(D-1) with OCS was detected with the laser-induced fluorescence (LIF) via the B-3 Sigma -X-3 Sigma system. The apparent production rates of SO(v = 8) in the initial reaction time and their OCS pressure dependence have been measured, giving the absolute overall rate coefficient for the O(D-1) + OCS reaction.
