Figure 4. Distribution of the angle φ between the dipole orientation of the water molecules in the first layer and the surface normal direction (z direction). The red, blue and olive curves correspond to δq = 0 e, δq = 0.2 e and δq = 0.9 e, respectively. The dipole distribution of the bulk water molecules is shown in black.
