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

β¦ Synopsis
Some fragments of the NH: potential surface have be.=n calculated by the SCF MO LCAO method using a basis of linear combinations of gaussian lobe functions. The NH; ion was found to be stable against dissociation into NH3 and H; or NH; and Hz. Its stability with respect to decomposition into NH; and H remains to be seen.
