Figure 3. Average number of H bonds formed by a water molecule in the first layer with other water molecules in the same layer (▼) and by a water molecule in the first layer with the water molecules above the layer () with respect to δq, together with their sum (■). The blue circles () represent the average number of H bonds formed by a water molecule in the first layer with the surface –OH groups. The black and blue dots correspond to the left and right vertical axes respectively.
