The rate coefficient for the reaction OH + ClO --> products (1) was measured under pseudo-first-order conditions in OH. A discharge flow system was used to produce ClO, and its concentration was measured by UV/visible absorption. OH was produced by pulsed laser photolysis of O-3 (or ClO) at 248 nm in the presence of H2O and was monitored by laser-induced fluorescence. The value of k(1) between 234 and 356 K is given by k(1)(T) = (8.9 +/- 2.7) x 10(-12) exp[(295 +/- 95)/T] cm(3) molecule(-1) s(-1), where uncertainties are 95% confidence limits and include estimated systematic uncertainties. Our value is compared with those from previous investigations.
