Setting aside the case of the Tang-Toennies damping function, the overall accuracy of the various damping functions is similar when measured in percentage terms. However, maximum errors in Fig. (b) highlight subtle nuances in the behavior of each damping potential as R → 0 and each of the other damping functions systematically overbinds these dimers by 1-2 kcal/mol; see Fig. . This is consistent with results indicating that EFP consistently overestimates dispersion interactions in ionic liquid constituent dimers, relative to third-order SAPT calculations. The original and generalized damping equations exhibit slightly smaller errors than their revised counterparts, although this indicates some error cancellation since only the revisions have a rigorous theoretical foundation. The BJ damping function affords results comparable to those of the original EFP damping function but without ad hoc approximations such as missing terms. We recommend this version for general use with EFP dispersion.
