Investigations of Surface Enhanced Raman Scattering (SERS) of pyridine adsorbed on the silver electrode of different roughness have been performed. The obtained results indicate that the micro- and the atomic scale roughness influence the intensity of SERS signal. This proves for the electromagnetic and charge transfer origin of the enhancement in the SERS phenomenon.
