Abstract
Translational energy spectroscopy measurements of the unimolecular dissociation of the 2-propenyl radical and photofragmentation channels of 2-chloropropene excited at 193 nm were presented. Product isomers formed were distinguished by tunable vacuum ultraviolet (VUV) photoionization of the products. Change in the branching ratio between the two competing C-H fission channels as a function of the radical's internal energy was measured. Barrier to H+allene formation from high energy C3H5 radical was higher than the barrier to H+propyne formation. A technique for forming a particular CnHm isomer dispersed by internal energy due to the primary photolysis was also demonstrated.
