✦ Synopsis

is checked for its ability to reproduce the experimental continuum of the Na 2 4 3 g (v = 12, N = 23) → a 3 + u bound-free transition observed by G. Lazarov, A. M. Lyyra, Li Li, and J. Huennekens (J. Mol. Spectrosc. 196, 259 (1999)). A significant difference between the experimental and simulated bound-free spectra is found even though about 300 rovibrational term values spanning the range of v = 2-25 vibrational quantum numbers and N = 6-15 rotational quantum numbers were used for the construction of this RKR potential. The new potential curve of the Na 2 4 3 g state was determined by applying the two-step global fit procedure of V.
