The unimolecular fragmentations of internal energy selected allene molecular ions ( 1 + ) have been investigated by photoelectron‐photoion coincidence spectroscopy. The energy dependence of the branching ratio between the two most important fragmentation channels is reported, together with values for the kinetic energy release during fragmentation. Loss of an hydrogen atom from 1 + is interpreted to proceed via two paths, yielding different isomeric forms of C 3 H 3 +with different kinetic energy release values.
