Using pulsed perturbation-facilitated optical-optical double resonance (PFO
ODR) spectroscopy, the 2(3)Delta(g) state of Li-7(2) (electronic configurat
ion (sigma(8)2s) (4d delta(8)), effective principal quantum number n* = 4.1
01) has been observed and assigned. Molecular constants and a RKR potential
energy curve were obtained, The major molecular constants are
T-e(cm(-1)) omega(e)(cm(-1)) B-e(cm(-1)) / 2(3)Delta(g) 35 014.1(33) 265.68
(88) 0.5115(18
