Figure 3.
Interaction energies of the prism isomer (isomer 1 in ref 96 of the water hexamer calculated using QM/MB-pol and QM/MB-DFT for all possible QM/MM partitions involving one to five water molecules in the QM region using fully self-consistent (fsc) and partially self-consistent (psc) cross-polarization between the QM and MM regions. The grey line is the MB-pol reference energy, and the blue line is the PBE0-D3 reference energy. The numbers at the top of each column determine the number of water molecules in the QM and MM regions (num QM/num MM).
