Surface-enhanced Raman scattering (SERS) spectra of 4-methylpyridine are obtained in silver hydrosol and compared with those obtained in an electrochemical cell. The use of density functional theory (DFT) calculations allows one to interpret the SERS data and collect information on the structures of the complexes formed on the metal surface as well as on the Raman enhancement mechanism.
