Abstract: | It is shown that the electrostatic energy functional is the only one available for fitting a given potential using approximate electric potentials arising from point charges. The significance of this fitting is examined in terms of splines. To illustrate the method the electron densities of atoms are modelled using point charges at the vertices of tetrahedra and of cubes. |
