CCSD(T) calculation of the ground-state potential curves for the Cd-rare gas van der Waals molecules

The spectroscopic parameters (Re,De,ωe) for the ground state of the weakly bound Cd–rare gas (He, Ne, Ar, Kr, Xe) van der Waals molecules have been calculated at the valence CCSD(T) level using quasirelativistic energy-consistent small-core pseudopotentials and large atom-centered basis sets. The theoretical potentials are discussed in the context of available experimental data. Very good agreement of theory with experiment has been found.
