Studies on the full vibrational energies and dissociation energies for some states of alkali hydride molecules

The full vibrational energy spectra for the A¹Σ⁺ states of alkali hydride diatomic molecules ⁶LiH, ⁷LiH, NaH, KH, RbH and CsH have been studied using algebraic method (AM), and the dissociation energies D_e of these molecules have also been studied using algebraic energy method (AEM). The results show that the AM produces accurate full vibrational energy spectra for these molecules for the first time so far as we know, and based on these AM spectra, the AEM can give correct molecular dissociation energies D_e for these systems.
