Nevertheless, both RISM (SPC) and RISM (TIP5P) models successfully reproduce the experimentally expected H-up to H-down flip when crossing the PZC. This flip in the orientation of the water molecules at the interface is a key feature of the electrode-electrolyte interface and has been observed in various experimental and computational studies. The ability of both models to capture this behavior is a testament to their accuracy in describing basic electrostatic features of the electrochemical interface.
