N2 - Using the pulse radiolysis UV absorption technique and subsequent simulations of experimental absorption transients at 254 and 276 nm, upper limits of the rate constants for the reactions of CF3O2 and CF3O radicals with ozone were determined at 295 K, CF3O2+O3-->CF3O+2O2 (4), CF3O+O3-->CF3O2+O2 (5). The upper limits were derived as k4 < 0.5 x 10(-14) cm3 molecule-1 s-1, and k5 <1 x 10(-13) cm3 molecule-1 s-1. Results are discussed in the context of the atmospheric chemistry and ozone depletion by hydrofluorocarbons.
