Complex Interadsorbate Interactions:
How Molecules Communicate

Interadsorbate interactions may be broadly categorised as arising due to either through-space mechanisms or substrate-mediated phenomena. Although they are most often repulsive in character, a classic example of important attractive interactions is the formation of extended hydrogen-bonded networks on the surface, found in the adsorption of water, amino acids, and other biologically-relevant molecules. Unexpected attractive interaction is also found in the stable coadsorption of NO2 and CO (two electronegative species) on Au{111}. We aim to study these and other systems, in which the interadsorbate interactions are both important and far from simple.
