Measurement of the rate coefficient for the reaction of OH with BrO
We report the rate coefficient for the reaction OH + BrO --> Products (1) at 298 K to be k(1)(298 K) = (4.5 +/- 1.8) x 10(-11) cm(3) molecule(-1) s(-1). Reaction 1 was studied in an excess of BrO, generated in a flow tube, and measured via its UV-vis absorption. OH, produced by laser photolysis, was monitored by laser induced fluorescence. Quoted uncertainties include estimated uncertainties in the BrO concentration and that due to the unavoidable concurrent reaction of OH with Br-2 Our measured value of k(1) is compared with that previously reported by Began et al.(1)
