Abstract:

A general discussion of the structure of the charged interface when the surface is not smooth is presented. In particular, the effect of a structured electrode is presented. The electrochemical interface offers a particularly big challenge to the scientist because it is such an important system a lot has been worked on it, and yet because of the intrinsic technical difficulties associated with non-extra high-vacuum surface physics, very little direct structural evidence is available for the active electrode. There is an increasing body of evidence coming from optical spectroscopy-Techniques such as Surface Enhanced Raman effects SERS, Surface Infrared Spectroscopy SIRS, and more recently, Second Harmonic Generation SHG are fine examples of diagnostics for structural changes changes in bonding arrangements but do not provide unequivocal structural information The shifts and intensities of the spectral lives depend on local field as well as local structure. rh
