On the other hand, the SPC model depicts the interface with a positively charged first layer. This observation can be explained by examining the 2D averaged density plots for both models which are available in the Supporting Information. These plots reveal that for the RISM (SPC) model the hydrogen sites are located slightly beneath the oxygen sites. This arrangement, without the flexibility of the 5-site model results in a more simplistic representation of the interfacial structure. In contrast, the RISM (TIP5P) model presents a complex picture of the charge distribution at the platinum-water interface (Figure ), with a strong spatial dependence along the direction parallel to the surface. The 2D averaged density plots for the RISM (TIP5P) model shows that the oxygen sites are not at maximum density directly above the platinum atoms (ontop sites), but rather between them (hollow sites).
