Correlation plots for 2B interaction energies. Plotted on the x axes are the BSSE-corrected CCSD(T) reference energies calculated with the aug-cc-pVTZ (aVTZ) basis set for ∼1400 water dimers. On the y axes are the corresponding energies calculated with the different water PEFs. Color scheme: empirical models = blue, polarizable models = light blue, semiempirical models = green, DFT models = yellow, explicit many-body models = orange, and MP2 = red. All data were taken from ref (32).
