Three positions of absorption of noble gas on graphite: above the center of the six membered ring , above the center of the carbon-carbon bond , and above the carbon atom . denotes the nearest carbon, denotes second nearest carbon; distances outside circles are treated as continuum. At the top site the first nearest carbon neighbor lies directly below the noble gas atom.
