WebSep 1, 1989 · The surface‐enhanced Raman scattering of cyclohexanethiol was investigated in a silver sol. Cyclohexanethiol was found to adsorb dissociatively after losing its thiol proton and adsorption was found to occur via its sulphur atom. Both the equatorial and axial chair conformers were found to exist on the surface at low surface coverage. WebThe Au–S interface of thiol-based, self-assembled monolayers grown on Au(111) surfaces is far less understood than it should be. Local barrier height imaging, which has recently resolved work function variations in the buried interface of alkanethiolate monolayers, is now used to study self-assembled monolayers on Au(111) formed by cyclohexanethiol, a …
