Rovibronic transitions near the dissociation limit in the absorption spectrum of the 7LiH molecule

New data on the photoabsorption spectra of 7LiH are reported involving the ground state X1 Sigma ( nu =1) and the excited state A1 Sigma ( nu =16 to 26). Rotational and vibrational analysis of the new bands are presented. The highest observed vibrational level approaches the dissociation limit. The estimated dissociation energy is in reasonable agreement with the previously known value.
