We investigate recently published methods for extending density functional theory to the description of long-range dispersive interactions. In all schemes an empirical correction consisting of a C6r(-6) term is introduced that is damped at short range. The coefficient C6 is calculated either from average molecular or atomic polarizabilities. We calculate geometry-dependent interaction energy profiles for the water benzene cluster and compare the results with second-order Møller-Plesset…

While density functional theory (DFT) allows accurate quantum mechanical simulations from first principles in molecules and solids, commonly used exchange-correlation density functionals provide a
Dispersion corrected density functionals applied to the water naphthalene cluster
We study a recently proposed set of methods that extend Density Functional Theory (DFT) to include long-range dispersive interactions. The water naphthalene interaction is discussed and is compared

Long-range corrected hybrid density functionals with damped atom-atom dispersion corrections.
TLDR
The re-optimization of a recently proposed long-range corrected hybrid density functional, omegaB97X-D, to include empirical atom-atom dispersion corrections yields satisfactory accuracy for thermochemistry, kinetics, and non-covalent interactions.
The water-benzene interaction: insight from electronic structure theories.
TLDR
Given the relative paucity of QMC reports for noncovalent interactions, it is interesting to see that QMC and coupled cluster with single, double, and perturbative triple excitations are in very good agreement for most of the binding energy curve, although at short distances there are small deviations on the order of 20 meV.
A post-Hartree-Fock model of intermolecular interactions: inclusion of higher-order corrections.
TLDR
The model is extended to include higher-order dispersion coefficients C(8) and C(10) and performs very well for prediction of intermonomer separations and binding energies of 45 van der Waals complexes, with minimal computational cost.
