Ionization and Dissociation of Oxygen Difluoride by Electron Impact

Abstract
The mass spectrum of OF2 includes the ions OF2+, OF+, O+, and F. The ionization potential of the molecule and appearance potentials and excess kinetic energy are measured for the OF+ and F ions. The known heat of formation of OF2 and the appearance potential of the F ion permit calculation of the bond dissociation energies D(FO–F) and D(O–F) and an estimate of the ionization potential, I(OF). Dissociation energies estimated for the OF2+ ion are consistent with those of the neutral molecule.
