摘要: A practical and efficient method for exploiting second order Rayleigh–Schrodinger perturbation theory to approximate the correlation energy contribution London dispersion interaction is presented. The estimated as Moller–Plesset computed using single particle orbitals from hybrid exchange density functional reference state.
