Using a sensitive optical wavelength modulation technique the surface-plasmon excited on a gold grating surface immersed in sulphuric acid is studied at the same time as cyclic voltammetry is undertaken. Because of the optical sensitivity of the modulation technique significant optical effects are observed at potentials well below those at which any gross oxidation effects occur.
