Communication: Symmetry-adapted perturbation theory with intermolecular induction and dispersion energies from the Bethe–Salpeter equation
2017
Journal of Chemical Physics
Preserved Fulltext
A method for calculating intermolecular induction and dispersion energies based on a GW description of the monomers and employing response functions from the Bethe-Salpeter equation is proposed. Calculations on a test set of 10 weakly bound complexes with GW -based symmetry-adapted perturbation theory (GW -SAPT) show an improved performance in comparison with symmetry-adapted perturbation theory based on density-functional theory (DFT-SAPT).
