From: Critical Dipole Length for the Wetting Transition Due to Collective Water-dipoles Interactions

Electrostatic interaction energy between water molecules and each charge on the solid surface with respect to the dipole length (l) for the charge (q) 1.0 e (magenta), 0.8 e (green), 0.6 e (blue), 0.4 e (red) and 0.2 e (black).
The open circles are determined directly from numerical simulations (denoted by Eelectro) and the filled stars represent the electrostatic interactions energy calculated from the radial distribution function (denoted by Etheory).
