The anion effect on the surface-enhanced Raman scattering (SERS) of interfacial water molecules on Ag electrodes has been studied by adding concentrated KCI, KRr, KI or KF solution to dilute solutions. SERS of the interfacial water was detected after adding concentrated KCI, KRr or KI solution, but
Enhanced Raman scattering has been observed from the hexacyanoferrate (II) and (III) ions adsorbed on Ag electrode surfaces. In the former case, five vibrational modes in the low-frequency range (214, 373,423,494 and 560 cm-') and four in the nitrilc-stretching region (2026,2067,2082 and 2122 cm-')
