dcterms:description
Films and monolayers of organic compounds on several metal surfaces are widely studied and analyzed by surface enhanced Raman scattering (SERS) and surface enhanced infrared absorption (SEIRA) spectroscopy considering significantly increased sensitivity of these techniques with respect to their normal (non-enhanced) counterparts. Both SERS and SEIRA found their EM mechanism origin in a light interaction with nanoparticles/nanostructures. SERS is observed primarily for analytes adsorbed onto the surface of coinage (Au, Ag, and Cu) metals, because they match very well the (plasmon) resonance condition and are able to give efficient SERS effect in visible and/or near-infrared range. The aim of this work is: (i) development of appropriate combined electrochemical preparation procedures of copper substrates using the cathodic reduction from electrochemical baths with oxidation-reduction cycles treatment and (ii) elucidation of detailed structural architecture of the model analyte (4 aminobenzenethiol)/Cu substrate system profiting from the combination of SERS and SEIRA data measured on the same samples and further comparison with normal vibrational spectra and results of density-functional theory calculations.
