Surface Attachment Mode (IMAGE) Georgia Institute of Technology Caption This image shows the surface attachment mode of two excess electrons to a water cluster (average diameter of close to 2nm) comprised of 105 molecules. The shown configuration was obtained from first-principles quantum simulations. The two wave functions each occupied by one excess electron, depicted in blue and green, are localized at opposite sides of the cluster and they are shown superimposed on the water molecules. The oxygens and hydrogens of the water molecules are represented by red and gray spheres, respectively.
