- The dynamics of the O(D-1) + CHF2Cl --> OH + CF2Cl reaction were investigated at a center-of-mass (c.m.) collision energy of 0.64 eV using O(D-1) 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(nu = 0, 1) rotational distributions were derived. The OH(nu = 0)/OH(nu = 1) branching ratio was determined to be 1.19. The OH spin-orbit states as well as the Lambda-doublet states were found to be equally populated in the reaction. The absolute reaction cross section, sigma(R)(E(c.m.) = 0.64 eV) = 0.21 +/- 0.05 Angstrom(2), was determined and a possible reaction mechanism is discussed.
