Ionization and Dissociation of Perchlorylfluoride by Electron Impact

Abstract

Relative abundances and appearance potentials are reported for both positive and negative ions observed in the mass spectrum of perchlorylfluoride. Appearance potentials of the atom ions result in a value for ΔH_f(ClO₃F) of nearly zero within the experimental uncertainty. Bond dissociation energies and ionization potentials of the chloryl radicals are estimated from appearance potentials of the polyatomic ions. The energetics of probable ionization‐dissociation processes are compared with observed data.
