The ground state van der Waals potentials of Zn-RG complexes (RG = He, Ne, Ar, Kr, Xe)

摘要

The dispersion coefficients of Zn-RG complexes are calculated from that of Zn-2 and rare gas dimers through the well-established combining rules. Based on the assumption that the corresponding states principle is valid for group 12 and rare gas complexes, that is the reduced potential energy curves of Zn-RG and Hg-RG have the same shape, the ground state van der Waals potentials of Zn-RG can then be determined by the Tang-Toennies potential model. The present potentials of Zn-RG are compared with previous theoretical and experimental results. The spectroscopic constants of Zn-RG are derived from their potentials respectively.
