The adsorption of bipyridine molecules on Au(110) as measured by reflection anisotropy spectroscopy

The reflection anisotropy spectra of 2,2'-bipyridine and 4,4'-bipyridine adsorbed onto an Au(110) surface in an electrochemical cell demonstrate that both systems form ordered structures. It is shown that reflection anisotropy spectroscopy can be used to distinguish between structural isomers adsorbed on the Au(110) surface.
