✦ Synopsis

The 7 Li 2 5 1 + g and 6 1 + g states have been studied both experimentally and theoretically. Vibrational levels v = 1-26 of the 5 1 + g state and v = 2-14 of the 6 1 + g state were observed using pulsed optical-optical double resonance technique. The 5 1 + g state has an unusual potential energy curve with a shelf near v = 11. Dunham coefficients for the v = 0-9 levels of the 5 1 + g state have been obtained. RKR potential energy curves of these two were generated. Ab initio potentials are in good agreement with the RKR potentials.

The predissociation of the 1 3 ⌺ g Ϫ v Ն 10 levels of 7 Li 2 has been observed by pulsed and continuous-wave perturbationfacilitated optical-optical double-resonance spectroscopy (PFOODR). Our ab initio calculation shows that the inner wall of the 1 3 ⌺ g Ϫ potential intersects the 1 3 ⌸ g repulsive

Five highly excited (1)Sigma(+)(g) states of Na(2) were observed for the first time by pulsed optical-optical double resonance (OODR) fluorescence excitation spectroscopy. Three of the five states are assigned to the 6svarsigma (1)Sigma(+)(g), 6dvarsigma (1)Sigma(+)(g), and 7dvarsigma (1)Sigma(+)(g)

With a sensitive space-charge-limited diode ionization detector, we studied 8-10svarsigma, 8-10dvarsigma (1)Sigma(+)(g), and 10-15dpi (1)Pi(g) Rydberg states of Na(2) and obtained their molecular constants for the first time. It is the first successful example of a diode ionization detector that is
