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