In this section, we analyze the performance of the potential function presented here by comparing calculated results with DFT calculations at the PBE0+MBD@rsSCS level as well as a published point-charge potential function that has the same rigid internal geometry and number of non-electrostatic interaction sites as our model. The comparison of these two potential functions illustrates the e↵ect of including polarizability, as well as enhancing the non-electrostatics of the model. From here on, we refer to the PBE0+MBD@rsSCS calculations as 'QM', the calculations using the 3-site fixed point-charge model as the 'point charge model', and the new, polarizable model as 'SCME'. The chosen point charge model underestimates the potential strength for both the monomer and the dimer, while the SCME electrostatic agreement is in close agreement with the MP2 results.
