โฆ Synopsis
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 transition moments for X *II-A*Z-and X *H-B*A are calculated. The results are compared with experiments and other calculations.
