Abstract
The B 1Π -X 1∑+ absorption spectrum of 7LiD has been reexamined. Evidence for an additional vibrational level (v′ = 3) in the upper state has been found. Because this vibrational level is extremely close to the dissociation limit, only J′ = l and J′ = 2 levels occur. This additional information provides an improved dissociation limit of 34671.5±0.4 cm-1, 1.5 cm-1 lower and 20 times more precise than previous results. From this result, dissociation energies of 19767.7-40.4 cm-1 for the X state, 8588.4±0.9 cm-1 for the A state, and 201.8±0.4 cm -1 for the B state of 7LiD are derived.Peer Reviewe
