The rate constants, k(1), for the reaction of CF3CHFCF2CH2OH with OH radicals were measured using both absolute and relative rate methods at 230-430 K. The absolute rate constants were measured at 250-430 K using flash photolysis and laser photolysis combined with laser-induced fluorescence detection. A smog chamber/FTIR technique was used for the relative rate measurements at 230-308 K with CH2Cl2 and CHCl3 as reference compounds. The k(1) values obtained with the two methods were consistent within the experimental uncertainties. The temperature dependence of k(1) was determined to be (2.49 +/- 0.30) x 10(-12) exp[-(880 +/- 40)/T] cm(3) molecule(-1) s(-1). The atmospheric lifetime was estimated to be 0.34 year.
