The activated Ag electrode which was treated by electrochemical cyclic voltammetry to obtain surface enhancement Raman scattering(SERS) effect was used to investigate the self-assembled monolayers(SAMs) behavior of 2-mercaptobenzimidazole(MBI). The results show that SAMs of MBI are of ideal SERS effect on roughened Ag electrode and its SERS effect is related to concentration and p H. With the increasing of concentration,the SERS effect is strengthened firstly but weakened latterly because of its steric hindrance when it happens to the high concentration. As a result,the most effective enhancement is at 1 × 10- 6mol·L- 1. On the other hand,the SERS effect of MBI in acid solution is better than in alkaline or neutral solution. It is further illustrated that MBI molecule has two different isomers and three kinds of existing forms,and all of them keep dynamic balance in solution. When the p H is lower than 2,MBI+,the main form of MBI molecule,is absorbedon roughened Ag electrode with coordinate bond between S: and Ag. MBI molecules stand vertically on Ag surface through π bond and produce relatively higher SERS effect. When the p H is higher than 2,thiol absorbed on Ag surface with S—Ag covalent bond and N—Ag coordinate bond is stronger than thione. This results in competitive absorption between thiol and thione of MBI,so SERS effect rapidly decreases from p H = 2 to p H = 3. 7. As a result,thiol form of MBI lays aslant to Ag surface with S—Ag covalent bond and N—Ag coordinate bond,making the weaker SERS effect than thione.
