The semiempirical quantum chemical PM6 method is, because of its construction and parametrization for more than 80 elements, superior to other similar methods. Despite its advantages it fails for the description of non-covalent interactions, specifically the dispersion energy and H-bonding. Upon inclusion of correction terms for dispersion and H-bonding the performance of the method was dramatically improved, and the resulting PM6-DH method achieved chemical accuracy (error < 1 kcal/mol) on the training S22 dataset.
