Potential-energy curves of the excited states of alkali hydride molecules

Abstract

The potential-energy curves of the excited states of NaH and KH have been obtained by the Rydberg-Klein-Rees method as described by Singh and Jain. The simple-harmonic curves and ionic curves for LiH, NaH, KH, and RbH have also been calculated. It has been found that the potential-energy curves mostly agree with Mulliken's findings as to the anomalous behavior of the excited states of alkali hydrides.
