# Dispersion corrections to density functionals for water aromatic interactions.

@article{Zimmerli2004DispersionCT, title={Dispersion corrections to density functionals for water aromatic interactions.}, author={Urs Zimmerli and Michele Parrinello and Petros Koumoutsakos}, journal={The Journal of chemical physics}, year={2004}, volume={120 6}, pages={ 2693-9 } }

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…

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.
