## Abstract A dualβlevel direct dynamic method is employed to study the reaction mechanisms of CF~3~CH~2~OCHF~2~ (HFEβ245fa2; HFEβ245mf) with the OH radicals and Cl atoms. Two hydrogen abstraction channels and two displacement processes are found for each reaction. For further study, the reaction m
## 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
