The effective fragment potential (EFP) method is a widely used polarizable force field that is obtained by automated parameterization of a physicallymotivated functional form, based on ab initio quantum chemistry. It has been used in hybrid quantum mechanics/molecular mechanics (QM/MM) calculations, both in the ground state and for vertical excitation spectra. Motivated by the success of empirical dispersion potentials in density functional theory (DFT), another potential application of EFP is to use its dispersion component as a parameter-free correction for DFT or even Hartree-Fock (HF) theory. The HF case is interesting insofar as dispersion-corrected HF theory does not involve any double-counting of electron correlation effects in the "middle-range" region, corresponding to non-bonded close-contact distances in van der Waals complexes, which is a concern in dispersioncorrected DFT. Empirical dispersion corrections have also been introduced in the context of second-order Møller-Plesset perturbation theory (MP2), because while MP2 does provide a first-principles description of dispersion, it is not a quantitative method for that purpose. Dispersion corrections have also been introduced for the closely-related method of symmetryadapted perturbation theory (SAPT). It is in the context that we had occasion to revisit EFP dispersion.
