Examples of dispersion (top row) and electrostatic (bottom row) corrections for charge density overlap in (a) benzene-peptide, (b) pentane-pentane, and (c) water-PO4H3 interactions. The x-axis indicates dimer intermolecular distance as a fraction of each dimer’s equilibrium separation. In all three examples, the undamped “classical” model diverges from the ab initio result at short range, while the damped model follows the ab initio curve closely.
