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-')
