We have observed the 5 (1)Pi(u), 6 (1)Sigma(u)(+), and 7 (1)Sigma(u)() states of Na-2 by using all-optical triple resonance excitation and
an ultrasensitive shielded cylindrical space-charge-limited ionization
detector (presumably detecting Na-3(+) produced by Na-2 + Na associa
tive ionization). Although the absolute vibrational numbering is uncer
tain, the rotational constants are obtained,The Franck-Condon window c
oncept is presented with calculated Franck-Condon factors based on the
theoretical 5 (1)Pi(u), 6 (1)Sigma(u)(+), and 7 (1)Sigma(u)(+) potent
ial energy curves of Magnier. (C) 1998 American Institute of Physics.
