英文摘要	The redox behavior of p-nitrothiophenol (p-NTP) monorayers on gold was studied by electrochemical irt situ surface enhanced Raman spectroscopy (SERS). The chemical adsorption of p-NTP on gold through Au-S bonding was confirmed by the comparison between the Raman spectra of parent molecules and that of the monolayer. The irreversible reduction of Q-NTP monolayers to p-aminothiophenol (p-ATP) monolayers was evidenced by the observed potential dependent spectral changes. The present results demonstrated the potential of SERS in investigating the adsorbate-substrate interaction and in monitoring surface reactions at a monolayer scale.; Crystallography; SCI(E); CPCI-S(ISTP); 2
