Abstract

Surface Raman scattering is used to study self-assembled monolayers formed from a series of 1-alkanethiols (1-butanethiol, 1-dodecanethiol, 1-octadecanethiol) at both electrochemically roughened and mechanically polished polycrystalline Ag electrodes. The spectra obtained at both surfaces are similar in all spectral regions. Defect structure in these films is investigated using the relative amounts of trans and gauche conformers in the v(C-S) and ν(C-C) frequency regions. These monolayer films are most ordered in the cases of 1-butanethiol and 1-octadecanethiol and least ordered in the case of 1-dodecanethiol. This behavior correlates with the ordering observed in the bulk 1-alkanethiols. Surface selection rules are used to determine molecular orientation at Ag.
