Long path length FTIR-smog chamber techniques were used to measure k(OH + cis-CF3CH@CHF) =
(1.20 ± 0.14) 1012 and k(O3 + cis-CF3CH@CHF) = (1.65 ± 0.16) 1021 cm3 molecule 1 s1 in 700 Torr
of N2/O2 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 cm1) of (1.71 ± 0.09) 1016 cm molecule1 and a global warming potential
of approximately 3 (100 year time horizon). Quoted uncertainties reflect two standard deviations from
least squares regression analyses.
