Notes:
Ab initio calculations of the potential energy surfaces of the first low-lying states of N2O++ (3Σ−, 1Δ, 1Σ+, and 3Π) have been performed. Photodissociation mechanisms have been investigated. The dissociation into NO++N+ appears to be a direct process for the first three lowest states. On the other hand, for the 1Δ and 1Σ+ states, high and wide potential barriers are found for the dissociation into N+2+O+ . The 3Σ− state seems to be the most likely state to dissociate along this direction. The predissociation by the 3Π state appears to be an unlikely process. From these theoretical results, the main experimental features are explained. In addition, a simple valence-bond model predicting the bond formation between two positively charged ions is proposed.
