Electronic structure of the polar molecules XF (X: Be, Mg, Ca) withrovibrational and dipole moment calculations
Abstract
A theoretical investigation for the feasibility of laser-cooling is performed through the calculation of accurate potential
energy curves, static dipole moments, spectroscopic constants and rovibrational calculations for 24, 26
and 27 highly excited electronic states for BeF, CaF and MgF molecules respectively. In order to understand the
electronic structure of their lowest lying electronic states and to learn the characteristic behavior of their chemical
bonding, a high level of calculation is realized by using the complete active space self-consistent field
(CASSCF) with multi-reference configuration interaction MRCI method including single and double excitations
with Davidson correction (+Q) for the three considered molecules. The comparison between the values of the
present work and those available in the literature for several electronic states shows a good agreement. Fifty
new excited electronic states have been investigated, in the present work, for the first time for the three studied
molecules.
