The combination of ultraviolet (uv) photodissociation, vacuum-ultraviolet (vuv) photoionization, and velocity-map ion imaging is used to explore the dissociative ionization of allyl and 2-propenyl C3H5 radicals that have significant amounts of internal energy. The effect of the internal energy of the radicals on the fragmentation dynamics of the parent photoion is first discussed for the general case, and then for the specific C3H5 radicals. The results are relevant to an increasing number of studies in which single-photon vuv photoionization is used as a 'soft' ionization method for radicals produced in photodissociation and reactive scattering experiments, as well as in reactive environments such as flames and plasmas.
