β¦ Synopsis
The characterization of the electropolymerization of phenols on silver (both in the presence and absence of amines) shows that the process is closely similar to that observed on iron. Raman spectroscopy shows that amines displace phenoxide ions which are adsorbed flat on the substrate. This displacement of phenoxide by amine explains the formation of thick protective films.

## Abstract Surfaceβenhanced Raman spectroscopy (SERS) was applied to the study of silver electrodes in the presence of 2βmercaptopyrimidine (2MP) over a wide electrode potential range from β0.3 to β1.8 V (__vs.__ SCE). The spectra reveal that in neutral solution 2MP was adsorbed perpendicularly on
Surface-enhanced Raman spectroscopy has been used to study the surface chemistry of thiocarbohydrazide (TCH) on Ag and Cu electrodes. The TCH molecule is adsorbed on Ag and Cu surfaces through its S atom. The electrochemistry of TCH in acidic solutions is also investigated. In contrast to thiosemica
