Calculation of Low-Lying Electronic Excitations of Magnesium Monofluoride: How Well Do Coupled-Cluster Methods Work?
Marko Horbatsch
Abstract:Magnesium monofluoride is a polar molecule amenable to laser cooling which has caused renewed interest in its spectroscopy.
In this work we consider the case of three low-lying electronic excitations, namely $\rm X \, {}^{2}\Sigma \to A \, {}^{2}\Pi, \ \to B \, {}^{2}\Sigma, \ \to C \,{}^{2}\Sigma$,
using well developed quantum chemistry approaches, i.e., without reference to the spin-orbit splitting of the $\rm A \, {}^{2}\Pi$ states.
Accurate experimental data for these transitions have been availabl… Show more
