Appearance and ionization potentials of ions produced by electron-impact on some phosphorus-fluorine compounds: the phosphorus-phosphorus bond dissociation energy in diphosphorus tetrafluoride

Abstract

The ionization potentials of P₂F₄, PF₃ PF₂H and PF₂I and the appearance potentials of the PF⁺₂ ion from these species are reported. The ionization potential of the PF₂˙ radical is estimated using approximations for the PF₂—X (X = F, I and H) bond dissociation energies. The P—P bond dissociation energy in diphosphorus tetrafluoride is estimated as 57 ± 10 kcal mol^–1.
