Abstract
The results of pulsed optical–optical double resonance spectroscopic studies of the E 1Σ+ g state of 7Li2 are presented. Observations were carried out on the v = 0 through v = 12 levels. A set of Dunham molecular constants was derived and an RKR potential was generated. Franck–Condon factors for transitions to the A 1Σ+ u state were determined for the range of observed vibrational levels. An apparent deviation from the expected dissociation energy is observed consistent with the suggestion that a double minimum exists for this state.
