Excited states ofNa2dissociating into 3d+3s, 4p+3s, and 5s+3s

All the excited adiabatic electronic states of ${\mathrm{Na}}_2$ dissociating into 3d+4s, 4p+3s, and 5s+3s atoms are calculated using a nonempirical pseudopotential, a flexible basis set, and the exact valence configuration-interaction treatment. Together with a highly precise work [G. H. Jeung, J. Phys. B 16, 4289 (1983)], where all the electronic states dissociating into 3s+3s, 3p+3s, and 4s+3s atoms have been calculated, this work reveals the lowest 38 electronic states of ${\mathrm{Na}}_2$. Wherever possible, the comparison of the present data with the recent spectroscopic observations shows excellent agreement. The majority of the theoretically predicted states remains to be found experimentally.
