Theoretical transition dipole moments and lifetimes for the A /sup 1/. sigma. /sup +//sub u/. -->. X. sigma. /sup +//sub g/ system of Na/sub 2/
Multiconfiguration self-consistent field (MCSCF) calculations have been carried out on the X /sup 1/..sigma../sup +//sub g/, A /sup 1/..sigma../sup +//sub u/, and B /sup 1/Pi/sub u/ states of Na/sub 2/. The calculated potential energy curves are in good agreement with the experimental X and A RKR curves of Hessel and Kusch. Both the A..-->..X and B..-->..X transition moments have been calculated as a function of nuclear separation using MCSCF wavefunctions. These calculations are in excellent agreement with the recent experimental determinations of the B..-->..X transition moment. A values and lifetimes of several A-state vibrational and rotational levels for the A..-->..X transition have been calculated using the theoretical transition moment and the experimental potential curves of Hessel and Kusch. These again are in excellent agreement with the recently measured lifetimes. (AIP)
