## 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
