The eight low-lying doublet states of the NH + ion are investigated with an ab initio configuration interaction method including all single and double excitations from a multi-reference confrguration space (MRSD CI). The spectroscopic constants for the X \*II, A\*Z-, Bh and C \*IX+ states and the tr

โฆ Synopsis
Potential curves of six low-lying doublet states and four quartet states of the BH+ ion have been calculared using an MCSCF + Cl method \hrlth a triple-zeta plus polarization basis set-The resulrs for the doublet slares are compared with orher calcularions and experiments.The results for the quartet states are the tirst.Transition moments for A 2D-X2Z+. B' 'z*-X 'E* and b 4Z--a4 D have been calculated. These results are discossed in connection with the experiments of Ottinger and Reichmu th 1_ introduction Chemiluminescent ion-molecule reactions of firstrow ions with the hydrogen molecule have been studied intensively by Ottinger et al. during the last decade [l] _

The effects of perturbation due to the spin-orbit interactions between the X % and a'% -states on the X-A % -and X-B \*A transition moments of NH+ are investigated.
High levels of ab initio calculations were performed with the target of exploring the potential-energy surface for the doublet and the quartet nitrogen with methane. There is a considerable difference between these two reaction paths in light of the formation of the reactant complex. Doublet nitroge
