  By incorporating the improved empirical atom-atom dispersion corrections from
DFT-D3 [Grimme, S.; Antony, J.; Ehrlich, S.; Krieg, H. J. Chem. Phys. 2010,
132, 154104], two long-range corrected (LC) hybrid density functionals are
proposed. Our resulting LC hybrid functionals, omegaM06-D3 and omegaB97X-D3,
are shown to be accurate for a very wide range of applications, such as
thermochemistry, kinetics, noncovalent interactions, frontier orbital energies,
fundamental gaps, and long-range charge-transfer excitations, when compared
with common global and LC hybrid functionals. Relative to omegaB97X-D [Chai,
J.-D.; Head-Gordon, M. Phys. Chem. Chem. Phys. 2008, 10, 6615], omegaB97X-D3
(reoptimization of omegaB97X-D with improved dispersion corrections) is shown
to be superior for non-bonded interactions, and similar in performance for
bonded interactions, while omegaM06-D3 is shown to be superior for general
applications.
