Flash photolysis/time-resolved UV absorption measurements of the rate constants for the title reactions are reported over the temperature range 2 lo-253 K. The photolysis of F2/CF,H/03/02/N, gas mixtures reveals that the formation of CF302 and CF,O radicals has no measurable effect on the ozone conc
A relative rate technique has been used to study the title reaction over the pressure range 100-700 Torr of air at 296 + 2 K. Four different reference compounds (13CO, CH4, CH2FCI, and CD 4) were used. Using k(CF30 + CH 4) = (2.2 -1-0.2) Γ 10-14 cm 3 molecule-1 s-1 a rate constant of k(CF30 + 03) =
## Abstract The relative rate technique has been used to determine the rate constants of the reactions of OH radicals with CF~3~CClο£ΎCCl~2~ (__k__~1~), CF~3~CClο£ΎCClCF~3~ (__k__~2~) and CF~3~CFο£ΎCFCF~3~ (__k__~3~). Experiments were carried out at (298Β±2) K and atmospheric pressure using ultrapure nitr
The reaction of CF3 radicals with Ha0 (D20) has been studied over the range of 533-723 K using the photolysis and the pyrolysis of CFJ as the free radical source. Arrhenius pa- rameters for the reactions where X = H or D, relative to CF:j radical recombination are given by log kHlkf'2 = (5.12 f 0.1
