Photodissociation dynamics of the 2-methylallyl radical

Author affiliations

Abstract

Time- and frequency-resolved photoionization of the hydrogen atom product from a jet-cooled electronically excited 2-methylallyl radical, C4H7, provides information on the dissociation dynamics. The measured dissociation rates and kinetic energy release of 2-methylallyl and its isotopologue CD3C3H4 combined with high level ab initio calculations suggests unimolecular dissociation with methylenecyclopropane and hydrogen as the major C–H bond fission channel with no evidence for nonstatistical behavior in dissociation. Other possible dissociation and isomerization pathways are discussed based on the results of the coupled-clusterab initio calculations.
