Dipole moment and potential energy functions of the <i>X</i> 1Σ+ and <i>A</i> 1Σ+ states of NaH

Abstract

Calculated radiative transition probabilities between all vibrational levels in the X 1Σ+ state (v=0–21) and in the A 1Σ+ state (v=0–32) of NaH are given. In addition, the calculated spontaneous emission lifetimes for vibrational–rotational levels (J=0,1) and the calculated dipole moments for these same levels are given. The calculations use new hybrid potential energy curves based on Rydberg–Klein–Rees (RKR) and ab initio potential curves. The RKR curve for the X state is new. The calculations use new ab initio dipole moment functions of internuclear distance.
