Orientation of ordered structures of cytosine and cytidine 5′-monophosphate adsorbed at Au(110)/liquid interfaces

It is demonstrated using reflection anisotropy spectroscopy that the adsorption of cytosine and cytidine 5(')-monophosphate at the Au(110) 1x2/electrolyte interface gives rise to ordered structures in which the base is oriented vertical to the surface and parallel to the [1 (1) over bar0] axis of the Au(110) plane.
