Abstract

A systematic method to evaluate the kinetic energy release distribution from the mass‐analyzed ion kinetic energy (MIKE) spectrum of a metastable ion decomposition, namely lunicolecular fragmentation of lpolyatomic ions, has been ceveloped. The analytical expression for a MIKE profile at a single kinetic energy release developed in lthe preceding paper has been utilized. The present method has been applied to the case of unimolicular dissociation of the t‐butylbenzene molecular ion and to the rather extreme case of a charge‐separation reaction of C₇H generated form toluene. Excellent agreements between the experimental data and calculated results have been observed.
