Correlations between HF-3c and ωB97X-V (with the latter evaluated in several different basis sets), for (a) two-body corrections ∆EIJ and (b) three-body corrections ∆EIJK , for the protein-ligand complex 181L. The diagonal line indicates where the two methods predict the same value and gray area in (a) represents ±1 kcal/mol difference. Only terms that involve the ligand (benzene) are plotted, using Rcut = 8 Å for the three-body terms. For the ωB97X-V calculations, the basis sets are def2-ma-SVP (labeled "DZ"), def2-ma-TZVP ("TZ"), and def2-ma-QZVP ("QZ").
