✦ Synopsis

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 potential at internuclear distance R ϭ 2.00 Å. The predissociation is due to a ⌬S ϭ 0, ⌬⌳ ϭ Ϯ1 rotational-electronic interaction with the repulsive 1 3 ⌸ g state.

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 c

We have observed the rotational levels in the v ϭ 2, 3, 5, 6, 7, and 8 vibrational manifolds of the 2 1 ⌬ g state of 7 Li 2 via the A 1 ⌺ u ϩ intermediate levels by ⌬⌳ ϭ 2 transitions. This violation of the ⌬⌳ ϭ 0, Ϯ1 selection rule is due to the interaction with the G 1 ⌸ g state. Band-by-band depe
