## Abstract The relative rate technique has been used to determine the rate constants of the reactions of OH radicals with CF~3~CCl๏ฃพCCl~2~ (__k__~1~), CF~3~CCl๏ฃพCClCF~3~ (__k__~2~) and CF~3~CF๏ฃพCFCF~3~ (__k__~3~). Experiments were carried out at (298ยฑ2) K and atmospheric pressure using ultrapure nitr
The rate constants for the reactions of OH radicals with CH 3 OCF 2 CF 3 , CH 3 OCF 2 CF 2 CF 3 , and CH 3 OCF(CF 3 ) 2 have been measured over the temperature range 250-430 K. Kinetic measurements have been carried out using the flash photolysis, laser photolysis, and discharge flow methods combine
A variety of relative and absolute techniques have been used to measure the reactivity of fluorine atoms with a series of halogenated organic compounds and CO. The following rate constants were derived, in units of cm3 molecule-' s-l: CH3F, (3.7 2 0.8) X CH3C1, (3.3 2 0.71 X 10 -'I; CH3Br, (3.0 2 0.
Rate constant ratios, k d /k c , for the disproportionation/combination reaction at a temperature of 295 ฯฎ 2 K, have been measured as 0.034 ฯฎ 0.009 for the collision between CF 3 CH 2 CF 2 ฯฉ CF 3 radicals and as 0.075 ฯฎ 0.019 for CF 3 CH 2 CF 2 ฯฉ CF 3 CH 2 CF 2 radicals.
