An analytical approximation of the symmetry-adapted components of the collision-induced hyperpolarizability for H2-Rg pairs (Rg = Ar, Kr, Xe)

► CI hyperpolarizabilities for H2-Rg via MP and CC cluster calculations. ► The calculations rely on atom/molecule specific purpose-oriented GTF basis sets. ► SA components of the CI hyperpolarizabilities for H2-Rg have been computed. ► The analytical model for the multipolar-type SA components has been proposed. ► A good comparison is observed with ab initio data.
