β¦ Synopsis
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 not in the case of concentrated KF solution.

A new method for the preparation of SERS active Cu electrode surfaces with high enhancement factors, which enable the observation of high quality spectra in the low-frequency region at different chloride concentrations, is proposed. Low-frequency modes at 160 and 145 cm-t are attributed to Cu-Cu vib
