✦ Synopsis

The transition electric dipole moments between low-lying valence states of NH+ are calculated by an ab initio effective valence-shell Hamiltonian ( H " ) method. The H '' calculated transition moments are found to be in good agreement with those by other accurate ab initio methods. The spontaneous emission probabilities for the A2C ~ + X 2KI, B2A ---f X2n, and C2C '+ X2TI transitions of NH+ are computed. Also, radiative lifetimes for A 2 8 -, B2A, and C2C+ states are all theoretically determined using the potential energy functions by H". Also, the H " results are well compared with those computed using the Morse potentials and the RKR potentials which are obtained from experimental data.
