PM6-DH+
=======

Use the PM6-DH+ semiempirical model instead of the default model, PM7 :cite:p:`Stewart:2013`.
It combines the PM6 model :cite:p:`Stewart:2007` with the DH+ model :cite:p:`Korth:2010b` for interatomic pairwise corrections
for dispersion and hydrogen bonding.
See the :ref:`model_overview` for a comparison of the various models available in MOPAC.

The :ref:`DISP` keyword can be used to print individual pairwise corrections from the DH+ model.
