Abstract

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 σ_R(E_c.m. = 0.64 eV) = 0.21 ± 0.05 A ̊², was determined and a possible reaction mechanism is discussed.
