Abstract
Transitions into the doubly excited Na-2 1 (3)Sigma(g)(-) state have been a nalyzed using near-dissociation expansions (NDE) to represent the vibration al energies and inertial rotational constants, while the centrifugal distor tion constants were held fixed at "mechanically consistent" values calculat ed from the Rydberg-Klein-Rees (RKR) potential implied by those G(upsilon) and B-upsilon functions. The input data cover the range upsilon = 0 to 57 a nd N up to 47, and the fit yields upsilon(D) = 61.41(+/- 0.10) and D-0 = 33 85.70(+/- 0.2) cm(-1). (C) 1999 American Institute of Physics.
