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 -monophosphate at the Au(110) 1 x 2/electrolyte interface gives rise to ordered structures in which the base is oriented vertical to the surface and parallel to the [110] axis of the Au(110) plane.
