摘要

Recently, Williams and Chabalowski (WC) published a paper on a hybrid approach for calculating intermolecular interaction energies using density functional theory (DFT) to describe correlated molecular properties of the monomers and symmetry adapted perturbation theory (SAPT) to describe the interactions between the monomers. They give a list of five attributes that should be fulfilled by such a hybrid approach , among them the sive interaction eneries shold be calculated with equal accuracy. Refering to their new method. WC state that "this DFT-SAPT hyrid approach should exhibit the then becomes the accuracy one can expect... with a give exchange-correlation functional"
