The rate coefficients for the removal of C1 atoms by reaction with three HCFCs, CF3CHC12 (HCFC-123), CF3CHFCl (HCFC-124), and CH3CFC12 (HCFC 141b), were measured as a function of temperature between 276 and 397 K. CH3CF2C1 (HCFC-142b) was studied only a t 298 K. The Arrhenius expressions obtained ar

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.
## Abstract Smog chamber/FTIR techniques were used to study the Cl atom initiated oxidation of CH~2~FOCH~2~F in 700 Torr of N~2~/O~2~ at 296 K. Relative rate techniques were used to measure __k__(Cl + CH~2~FOCH~2~F) = (4.6 Β± 0.7) Γ 10^β13^ and __k__(Cl + CH~2~FOC(O)F) = (2.9 Β± 0.8) Γ 10^β15^ (in un
## Abstract Relative rate experiments using UV photolysis of F~2~ or Cl~2~ have been used to determine rate constant ratios for several hydrofluorocarbon (HFC) reactions with Cl or F atoms and for HFC alkyl radicals with molecular halogens. For mixtures with F~2~ present, dark reactions are, also,
## Abstract The rate coefficients for the reactions of Cl atoms with CH~3~Br, (__k__~1~) and CH~2~Br~2~, (__k__~2~) were measured as functions of temperature by generating Cl atoms via 308 nm laser photolysis of Cl~2~ and measuring their temporal profiles via resonance fluorescence detection. The m
