H atom product channels in the ultraviolet photodissociation of the 2-methyl-1-propenyl radical
Abstract
〉 remaining constant at 0.13-0.15 across the studied wavelength range. The angular distribution of the H-atom photofragments is isotropic and indicates a dissociation timescale longer than the rotational period of the radical. The photodissociation mechanism of 2-methyl-1-propenyl is found to be consistent with statistical unimolecular decomposition of the radical in a highly vibrationally excited ground electronic state to the methylenecyclopropane + H products, following internal conversion from the excited electronic states.
