## 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

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
The multiple channel reaction H + CH(3)CH(2)Cl --> products has been studied by the ab initio direct dynamics method. The potential energy surface information is calculated at the MP2/6-311G(d,p) level of theory. The energies along the minimum energy path are further improved by single-point energy
Absolute rate constants for the reaction of O(3P) atoms with CHI = CHF, CH2 = CHC1, and CH2 = CHBr have been obtained at 298 f 2Β°K using a modulation phase shift technique. The rate constants ( k z X lo-\* l./mole.sec) obtained are: CH2 = CHF (1.61 =t 0.20), CH2 = CHCl (2.54 + 0.26), and CHZ = CHBr
The C1 atom-initiated oxidation of CHzClz and CH3Cl was studied using the FTIR method in the photolysis of mixtures typically containing Clz and the chlorinated methanes at 1 torr each in 700 torr air. The results obtained from product analysis were in general agreement with those reported by Sanhue
## Abstract The mechanisms of the reactions: CH~3~CFCl~2~ + Cl (R1) and CH~3~CF~2~Cl + Cl (R2) are studied over a wide temperature range (200β3000 K) using the dualβlevel direct dynamics method. The minimum energy path calculation is carried out at the MP2/6β311G(d,p) and B3LYP/6β311G(d,p) levels,
