The chemisorption of dodecyl disulfide and phenyl disulfide on chemically deposited silver film and HNO 3 ‐etched silver foils was investigated by Fourier‐transform surface‐enhanced Raman scattering spectroscopy (FT‐SERS). These disulfides can cleave and are chemisorbed on silver surfaces. We found these two kinds of substrates showed different activation to the sulfides and there is some fine distinction of SERS signals of the same chemical on the substrates. The enhancing effect of the adsorbent signal and adsorption depend on the substrate state. Chemically deposited silver substrate shows better activation and SERS enhancing effect than the HNO 3 ‐etched silver foils. Copyright © 2004 John Wiley & Sons, Ltd.
