In recent years, high-resolution photoelectron spectroscopy and ab initio calculations have considerably revised and enlarged the understanding of the electronic structure of the NO+ ion. Based on these results, new potential energy curves for the electronic states of NO+ below 24 eV have been constructed and are given here. RKR potentials were calculated from new molecular constants for the eight experimentally well-defined states. For the other states, the main features of the potentials were estimated from theoretical calculations and from isoelectronic analogies. A brief review is given of the information on which each potential energy curve is based.
