Chemically reduced gold particles on an organic sulfide‐covered plate can effectively enhance surface Raman scattering signals. This method was used to investigate the adsorption states of 4‐aminophenyl disulfide and benzyl disulfide attached to the iron surface by Fourier transform surface‐enhanced Raman scattering. The results indicate that these sulfide molecules can be chemisorbed perpendicularly and form a self‐assembled film dotted with ferric hydroxide on the iron surface.
