General description
4,4′-Dimercaptostilbene is a dithiol molecule that can be coated on gold (Au) surfaces as it provides a rigid structure and has low susceptibility to chemical interactions. It modifies the surface of gold and enables an increase in enhancement factor (EF) for surface enhanced Raman spectroscopy.

We report tip-enhanced Raman imaging experiments in which information on sample topography and local electric fields is simultaneously obtained using an all-optical detection scheme. We demonstrate how a Raman-active 4,4'-dimercaptostilbene (DMS)-coated gold tip of an atomic force microscope can be

We record sequences of Raman spectra at a plasmonic junction formed by a gold AFM tip in contact with a silver surface coated with 4,4'-dimercaptostilbene (DMS). A 2D correlation analysis of the recorded trajectories reveals that the observable vibrational states
