The reaction of CF3 radicals with H2O (D2O) has been studied over the range of 533-723 K using the photolysis and the pyrolysis of CF3I as the free radical source. Arrhenius parameters for the reactions \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm CF}_3 + {\rm X}_2 {\rm O\buildrel{k_x}\over{\to}CF}_3 {\rm X} + {\rm OX} $$\end{document} where X = H or D, relative to CF3 radical recombination are given by \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{l} {\rm log}k_{\rm H} /k_c^{1/2} = (5.12 \pm 0.11) - (16,804 \pm 335)/\theta \\ {\rm log}k_{\rm D} /k_c^{1/2} = (5.03 \pm 0.16) - (17,803 \pm 456)/\theta \\ \end{array} $$\end{document} where k/kc1/2 is in cm3/2/mol1/2·s1/2 and θ = 2.303RT/cal/mol. The activation energy and the primary kinetic isotope effect have been compared with those derived from the BEBO method.
