The electric dipole moment of an electron (eEDM) is one of the sensitiveprobes of physics beyond the standard model. The possible existence of the eEDMgives rise to an experimentally observed energy shift, which is proportional tothe effective electric field (Eeff) of a target molecule. Hence, an analysis ofthe quantities that enhance Eeff is necessary to identify suitable moleculesfor eEDM searches. In the context of such searches, it is generally believedthat a molecule with larger electric polarization also has a larger value ofEeff. However, our Dirac-Fock and relativistic coupled-cluster singles anddoubles calculations show that the hydrides of Yb and Hg have larger Eeff thanthose of fluorides, even though their polarizations are smaller. This is due tosignificant mixing of valence s and p orbitals of the heavy atom in themolecules. This mixing has been attributed to the energy differences of thevalence atomic orbitals and the overlap of the two atomic orbitals based on theorbital interaction theory.
