✦ Synopsis

Following excitation of the 5d 1 ⌸ g Rydberg state of 7 Li 2 by optical-optical double resonance, fluorescence has been observed in the infrared region to the 2 1 ⌺ u ϩ and C 1 ⌸ u states. Analysis of high-resolution Fourier transform spectra yields term energies and rotational constants of the lowest seven vibrational levels of the inner well of the 2 1 ⌺ u ϩ ''double minimum'' state. The equilibrium term value and dissociation energy have been determined to be T e ϭ 30101.45 Ϯ 0.12 cm Ϫ1 and D e ϭ 5621.3 Ϯ 0.2 cm Ϫ1 . The v ϭ 0 and 1 levels of the C 1 ⌸ u state have been analyzed, resulting in new values of T e ϭ 30551.0 Ϯ 0.1 cm Ϫ1 and D e ϭ 7773.3 Ϯ 0.2 cm Ϫ1 .

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

Two new pairs of singlet-triplet A 1 ⌺ u ϩ ϳ b 3 ⌸ u mixed levels of 7 Li 2 have been observed and used here as "window" levels in cw perturbation-facilitated optical-optical double-resonance (PFOODR) experiments. Previously, only one b 3 ⌸ u vibrational level, v ϭ 19, was known to mix with the sing
