More recently, Mardirossian and Head-Gordon
developed two RSH functionals, ωB97X-V and ωB97M-V, via a
combinatorial approach by screening over 100,000 possible functionals in the
first case and over 10 billion possible functionals in the second case. Both of
the latter functionals use the VV10 non-local correlation functional in order
to improve the description of non-covalent interactions and isomerization
energies. ωB97M-V is a 12-parameter meta-GGA with 15% short-range exact
exchange and 100% long-range exact exchange and is one of the most accurate
functionals available through rung 4 of Jacob’s Ladder, across a wide variety
of applications. This has been verified by benchmarking the functional on
nearly 5000 data points against over 200 alternative functionals available in
Q-Chem.
