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.
Using a relative rate technique the reactions of chlorine and fluorine atoms with CF3CHO have been determined to proceed with rate constants of (1.8 % 0.4) x and (2.7 2 0.1) x lo-" cm3 molecule-' s-', respectively. Experiments were performed a t 295 ? 2 K and 700 torr total pressure of nitrogen. The
## 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 (200–3000 K) using the dual‐level direct dynamics method. The minimum energy path calculation is carried out at the MP2/6‐311G(d,p) and B3LYP/6‐311G(d,p) levels,
## Abstract By means of the dual‐level direct dynamics method, the mechanisms of the reactions, CH~3~CF~2~Cl + OH → products (R1) and CH~3~CFCl~2~ + OH → products (R2), are studied over a wide temperature range 200–2000 K. The optimized geometries and frequencies of the stationary points are calcul
