Abstract
A method developed by Klein has been applied to obtain the potential energy curve of the excited electronic state of LiH (state V). This curve crosses the Coulombic curve of Li+H— and indicates dissociation of excited LiH into Li(2 P)+H. The effect of this behavior on Mulliken's explanation of the unusual shape of the state V curve is discussed. The interaction of the Li+H— and Li(2 P)·H curves at moderately large interatomic distances is larger than Mulliken's estimate.
