Thiocyanide ion adsorption on Pt and Ni electrode surfaces was investigated by confocal Raman microscopy. The effects on the adsorption behavior of SCN- by the electrolyte anion, concentration and applied potential were studied. The potential has a significant effect on the frequency shift of SCN- as a result of the electrochemical Stark effect. The adsorbability of the electrolyte anion has a significant influence on the surface Raman intensity of SCN-; the intensity follows the order Cl- <ClO4- <F-. It can be explained in terms of competitive adsorption between the SCN- and the anion. It has been shown that surface Raman spectroscopy can be a sensitive tool for the in-situ analysis of the surface species and its configuration, such as surface complexes and films on transition metal electrodes.
