Rate constants for reactions of erythro-CF3CHFCHFC2F5 and threo-CF3CHFCHFC2F5 with OH radicals were determined by means of a relative rate method in an 11.5-dm(3) reaction chamber at 253-328 K: k(1) (erythro-CF3CHFCHFC2F5 + OH) = (9.60 +/- 3.39) x 10(-13) exp[-(1680 +/- 100)/T] and k(2) (threo-CF3CHFCHFC2F5 + OH) = (6.60 +/-2.06) x 10(-13) exp[-(1580 +/- 90)/T] cm(3) molecule(-1) s(-1).
