Laser-fluorescence measurement of the 7LiD (X 1∑+) potential up to high vibrational quantum numbers

Sixteen new vibrational levels of ⁷LiD (X ¹∑⁺) were found by analysis of laser-excited fluorescence spectra. They extend up to ν″ = 20, corresponding to 82% of the dissociation energy of LiD. New rotational and vibrational constants were derived from the data and were used for an RKR calculation of the ⁷LiD (X ¹∑⁺) potential. Extra-polating this potential up to the dissociation limit gives agreement with the known dissociation energy to within 90 cm^?1.
