The rate coefficient, k(1), for the reaction OH + CF3I --> products was measured under pseudo-first-order conditions in hydroxyl radical, OH. OH temporal profiles were monitored by laser-induced fluorescence (LIF), and CF3I concentrations were determined by UV/Visible absorption. We determined k(1) (T) to be (2.10 +/- 0.80) x 10(-11) exp[-(2000 +/- 140)/T] cm(3) molecule(-1) s(-1), over the temperature range 271 to 370 K. The quoted uncertainties are 2 sigma (95% confidence limits, sigma(A) = A sigma(lnA)) Previous measurements of k(1)(T) are compared with our values, and possible reasons for the discrepancies are discussed. The heat of formation of HOI is deduced to be less than -16 kcal mole(-1), if the products of reaction 1 are mostly HOI and CF3. These measurements support the earlier conclusion that the reaction of OH with CSI plays a negligibly small role in the atmospheric removal of CF3I.
