Abstract CFBr radicals produced by the reaction of atomic oxygen with F 2 CCFBr were monitored in a discharge flow system by fluorescence excited at 424 nm. The rate coefficients for reactions of the CFBr radicals were measured between 298 and 358 K, and the following values were obtained in units of cm 3 /molec·s: O 2 < 2 × 10 −16 at 353 K; NO < 10 −14 at 298 K; F 2 CCFBr < 10 −15 at 298 K; Cl 2 (1.9 ± 0.6) × 10 −12 exp(−762 ± 92/ T ) Br 2 (1.4 ± 0.3) × 10 −12 exp(−533 ± 62/ T ).
