✦ Synopsis

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 deperturbations of the G 1 ⌸ g ϳ 2 1 ⌬ g (v ⌸ , v ⌬ ) ϭ (11, 2), (12, 3), (15, 5), (16, 6), (18, 7), and (19, 8) bands have been performed. Deperturbed molecular constants and rotational-electronic interaction parameters are reported here.

Electronic transition moments are computed for dipole transitions between the C and D 1 P u , I and R 1 P g and J and S 1 D g states of the hydrogen molecule for internuclear distances R √ [1, 15] bohr. The character of the wavefunctions at large internuclear distances is investigated. It is shown t

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 lowe

Two double resonance techniques, perturbation facilitated optical-optical double resonance (PFOODR) and collision induced fluorescence (CIF), have been used to excite the 2 3 P g (PFOODR only) and 1 3 D g states of 7 Li 2 . Fluorescence from each of these states to the b 3 P u state has been studied
