Abstract Molecular dissociation energies of 10 electronic states of alkali molecules of KH,7LiD, 7LiH, 6LiH, NaK, NaLi and NaRb are studied using the highest three accurate vibrational energies of each electronic state, and an improved parameter-free analytical formula which is obtained starting from the LeRoy--Bernstein vibrational energy expression near the dissociation limit. The results show that as long as the highest three vibrational energies are accurate, the current analytical formula will give accurate theoretical dissociation energies
Detheory, which are in excellent agreement with the experimental dissociation energies Deexpt.
