| Abstract: | The molecular dissociation energies of some electronic states of hydride and N2 molecules were studied using a parameter-free analytical formula suggested in this study and the algebraic method (AM) proposed
recently. The results show that the accurate AM dissociation energies D
e
AM
agree excellently with experimental dissociation energies D
e
expt
, and that the dissociation energy of an electronic state such as the 23Δg state of 7Li2 whose experimental value is not available can be predicted using the new formula.
