Electronic states and potential energy curves of In2P, InP2, In2P+, and InP2+

Electronic states of InP2, InP2+, In2P, and In2P+ are studied by the complete active space multi-configuration self-consistent field followed by multi-reference singles+doubles configuration interaction (MRSDCI) computations. Potential energy curves, geometries, energy separations and the adiabatic ionization energies of these species are also determined. We compare our results with the experimental spectra of Arnold and Neumark (Can. J. Phys. 72 (1994) 1322).
