Title: THE CENTRAL FORCE WATER MODEL AT THE ELECTROLYTE-ELECTRODE INTERFACE: AN INTEGRAL EQUATION APPROACH
Authors: M.Vossen, F.Forstmann, A.Kraemer (Institut fuer Theoretische Physik, Freie Universitaet Berlin, Arnimallee 14, D-14195 Berlin, Germany)

The central force water model is well suited for integral equation methods. At the electrode surface we find water molecules arranged in an ice-like structure with a surface dipole pointing towards the liquid and a negative surface potential -0.11 V at zero electrode charge. We find an asymmetric differential capacitance due to the water structure. Added Na^+ and Cl^- ions do not destroy the water structure. Only the small Na^+ can penetrate the structured water layer at high negative electrode charge.
