Popis:	Electrochemically anticorrosive behavior of 4-methyl-4H-1,2, 4-triazole-3-thiol (MTTL) self-assembled monolayers (SAMs) on the silver electrode was studied by means of electrochemical impedance spectroscopy (EIS) and polarization measurements. The promising inhibition effect of the MTTL for silver had been affirmed. Results of surface-enhanced Raman scattering (SERS) experiments indicated that the MTTL molecule in a tilted orientation was self-assembled on the silver surface through S' and N(2) atoms to form monolayers. An in situ electrochemical SERS experiment implied the changes of adsorption fashion of MTTL momolayers on the silver surface with the potential shifted to more negative direction.
