Abstract

In the present study the ground state as well as the lowest
4\Sigma+ state were determined for 16 AK-AKE molecules. (a)
Multireference configuration interaction calculations were carried out in order to
understand the bonding of diatomic alkali-alkaline earth (AK-AKE) molecules. The correlations between molecular properties (disociation energy, bond distances, electric dipole moment) and atomic properties (electronegativity, polarizability) will be discussed. A correlation between the dissociation energy and the dipole moment of the lowest 4\Sigma+ state was observed, while the dipole moment of the lowest 2\Sigma+ state does not show such a simple dependency. In this case an empirical relation could be established. The class of AK-AKE molecules was selected for this investigation due to their possible applications in ultracold molecular physics.
