GMIPp energy profiles for the approach of Na+ to benzene (x axis: dotted line; y axis: dashed line; z-axis: solid line). (Top) Electrostatic energy. (Middle) Polarization energy. (Bottom) Total energy. All the values are in kcal/mol. Distances (in Å) are referred in all cases to the hard sphere radius (see text). Hard sphere radii are: 4.58 (x axis), 4.97 (y axis), and 3.24 Å (z axis).
