Studies on heteronuclear diatomic molecular dissociation energies using algebraic energy method

The algebraic energy method (AEM) is applied to the study of molecular dissociation energy D_e for 11 heteronuclear diatomic electronic states: a^3\Sigma^+ state of NaK, X^2\Sigma^+ state of XeBr, X^2\Sigma^+ state of HgI, X^1\Sigma^+ state of LiH, A^3\Pi(1) state of ICl, X^1\Sigma^+ state of CsH, A(^3\Pi_1) and B0^+(^3\Pi) states of ClF, 2^1\Pi state of KRb, X^1\Sigma^+ state of CO, and c^3\Sigma^+ state of NaK molecule. The results show that the values of D_e computed by using the AEM are satisfactorily accurate compared with experimental ones. The AEM can serve as an economic and useful tool to generate a reliable D_e within an allowed experimental error for the electronic states whose molecular dissociation energies are unavailable from the existing literature.
