State-resolved dynamics of the O(1D) + CHF2Cl → OH + CF2Cl reaction

The dynamics of the O(1D) + CHF2Cl → OH + CF2Cl reaction were investigated at a center-of-mass (c.m.) collision energy of 0.64 eV using O(1D) atoms generated by laser photolysis of N2O at 193 nm. OH products were detected under single collision conditions by laser-induced fluorescence and nascent OH(v = 0, 1) rotational distributions were derived. The OH(v = 0)/OH(v = 1) branching ratio wwas determined to be 1.19. The OH spin-orbit states as well as the λ-double states were found to be equally populated in the reaction. The absolute reaction cross section σR(Ec.m. = 0.64 eV) = 0.21 ± 0.05 Å2, was determined and a possible reaction mechanism is discussed.
