摘要：

The adsorption of 4-mercaptobenzonitrile (MBN) on a polycrystalline gold electrode has been studied in a spectroelectrochemical approach; results are compared with those of a similar study of the adsorption of benzonitrile and bencylcyanide. Results imply adsorption of MBN via the sulfur atom; in case of the latter, compounds adsorption via the nitrogen atom of the cyano-group is found. In case of MBN, the electron-withdrawing cyano-group causes a substantial weakening of the MBN-gold interaction.
