For Au(111) at PZC, the distribution of water orientation on the side of metal slab with Cl adsorption show a blue-shift in the angle between water bisection and the surface normal and a clear diminishment in the peak around 60 degrees (Fig. ). This resembles the distribution of water orientation at 130 degrees as observed in the anodic polarized Au(111) surface at D = 0.018 au but with enhanced intensity.
