• Fragmentation of N2O+ in the narrow energy regime of 14.8 to 15.5 eV, where electronic predissociation occurs involving a state transition between N2O+ (X2IIi) and N2O+ (24Σ-), has been studied by threshold photoelectron-photoion coincidence (TPEPICO) mass spectrometry using a non-pulsed ion-extraction field. Detailed breakdown curves and kinetic energy releases accompanied by fragmentation were obtained. Kinetic energy releases observed for both the NO+ and O+ formations were consistent with the predictions based on the spectator model of direct dissociation. Results obtained have thus suggested that the fragmentations on the N2O+ (24Σ-) state occur considerably faster than the rate with which the system jumps from X2IIi to 24Σ-, and therefore this transition probability has been given approximately by the summation of both the NO+ and O+ breakdown curves with a most probable energy of ca. 15.2 eV in the curve-crossing.
