The rate parameters for the reaction of O(3P) with carbonyl sulfide, O(3P) + OCS → CO + SO, (1) have been determined directly by monitoring O(3P) using the flash photolysis‐resonance fluorescence technique. The value for k1 was measured over a temperature range of 263–502°K and the data were fitted to an Arrhenius expression with good linearity, k1 = (1.65±0.13)×10−11 exp(−4305±55/R T) cm3 molecule−1·sec−1. A comparison of the present results with those from previous studies of Reaction (1) is also presented.
