✦ Synopsis

Surface enhanced Raman scattering (SERS) of Hz0 adsorbed on Ag electrodes has been investigated with the aim of distinguishing between the effect of a high salt concentration on hydrogen bond disruption and the effect of a high salt concentration on the surface morphology produced during oxidation and reduction. In order to distinguish between these effects, the salt concentrations of the electrolytes were increased and the SERS signals monitored after the Ag electrodes had been oxidized and reduced in low salt concentration electrolytes. These results were then compared with SERS signals after oxidation and reduction in the high salt concentration electrolytes. Stabilization of active sites by pyridine and effects of different cations on the SERS of Hz0 are also demonstrated.
