Surface‐enhanced Raman scattering of 4‐(methylthio)benzonitrile (4MTB) adsorbed on a silver surface was investigated. The molecule was found to adsorb on the surface via its sulphur atom and nitrile group. By reference to the spectral correlation scheme in coordination chemistry, surface binding of the latter group was concluded to occur through both s̀ donation and π back‐donation. The benzene ring of 4MTB was deduced to be tilted with respect to the surface plane. In the adsorbed state, 4MTB was also observed to undergo surface‐induced photoreaction. The reaction product, presumably p‐cyanophenyl mercaptide, appeared to assume a much flatter orientation than its precursor due to stronger interaction of the mercaptide with the surface than that of sulphide.
