The FT-Raman Study of 4-Aminophenyl Ammonium Dithiocabamate Adsorption State on Different Silver Surface

Abstract
4-Aminophenyl ammonium dithiocabamate can easily be chemisorbed on chemically deposited silver film and HNO3 etching silver to form monolayer molecular films. The adsorption state was characterized by Foruier transform surface-enhanced Raman scattering spectroscopy (FT-SERS). The results indicated that the adsorbed molecules stand on the surface in tilting conformation.
