Long path length FTIR-smog chamber techniques were used to measure k(OH + cis-CF3CH=CHF) = (1.20 +/- 0.14) x 10 (12) and k(O-3 + cis-CF3CH=CHF) = (1.65 +/- 0.16) x 10 (21) cm(3) molecule (1) s (1) in 700 Torr of N-2/O-2 diluent at 296 K. The OH initiated oxidation of cis-CF3CH=CHF gives CF3CHO and HCOF in molar yields which are indistinguishable from 100%. The atmospheric lifetime of cis-CF3CH=CHF is determined by its reaction with OH and is approximately 10 days. cis-CF3CH=CHF has an integrated IR absorption cross section (600-2000 cm (1)) of (1.71 +/-0.09) x 10 (16) cm molecule (1) and a global warming potential of approximately 3 (100 year time horizon). Quoted uncertainties reflect two standard deviations from least squares regression analyses. (c) 2009 Elsevier B.V. All rights reserved.
