@article{Coxon2004ApplicationOD, title={Application of direct potential fitting to line position data for the X 1$\Sigma$+ and A 1$\Sigma$+ states of LiH}, author={J. A. Coxon and C. Dickinson}, journal={Journal of Chemical Physics}, year={2004}, volume={121}, pages={9378-9388} }

A collection of 9089 spectroscopic LiH line positions, of widely varying precision, which sample 84.9% and 98.6% of the A and X state well depths, respectively, have been employed in a direct least-squares fit of the effective potential energy and Born-Oppenheimer breakdown functions for the two states. For the four isotopomers 6LiH, 7LiH, 6LiD, and 7LiD, the data comprise both pure rotational and vibration-rotational transitions within the ground state, as well as rotationally resolved… Expand
