Dissociative electron impact ionization of N2O5.
International Journal of Mass Spectrometry, 232(2),
Electron impact ionization of dinitrogen pentoxide for incident electron energies up to about 25 eV has been investigated by use of a crossed beams quadrupole mass spectrometer system. The experiments reported in this paper detected the fragmentation products NO2+, NO+, O+, N+, and NO3+. No stable N2O5+ ion was observed. The NO3+ fragment, for which we determine an appearance energy 13.25±0.30 eV, has not been observed previously. This appearance energy is close to the calculated threshold.
