  We propose a long-range corrected hybrid meta-GGA functional, based on a
global hybrid meta-GGA functional, M05 [Y. Zhao, N. E. Schultz, and D. G.
Truhlar, J. Chem. Phys. 123, 161103 (2005)], and empirical atom-atom dispersion
corrections. Our resulting functional, omegaM05-D, is shown to be accurate for
a very wide range of applications, such as thermochemistry, kinetics,
noncovalent interactions, equilibrium geometries, frontier orbital energies,
fundamental gaps, and excitation energies. In addition, we present three new
databases, IP131 (131 ionization potentials), EA115 (115 electron affinities),
and FG115 (115 fundamental gaps), consisting of experimental molecular
geometries and accurate reference values, which will be useful in the
assessment of the accuracy of density functional approximations.
