英文摘要：

Considering the study of electrochemical surface adsorption and reaction processes at the molecular level, Surface-enhanced Raman spectroscopy （SERS） shows its particular merits and provides a powerful tech- nical method for this study. However, the mechanism of enhancement needs to be further explored. This re- view summarizes the systematic work on electrochemical SERS （EC-SERS） by combining quantum chemistry calculations. On the basis of these studies, we can make deep insight for extracting the physical and chemical information in EC-SERS spectra. Focusing on adsorption of pyridine on the electrochemical surface, adsorption and reactional process of water on the surface, and surface coupling reaction for p-aminothiophenol, we had illustrated the nature of the adsorption and photochemical reactions on the electrochemical surface.
