Adsorption of Some Aliphatic Dimercaptans on the Silver Surface Investigated by Raman Spectroscopy
Cheol Kee Kwon, Kwan Kim*, Myung Soo Kim*, Soon-Bo Lee
Adsorption of 1,3-propanedithiol, 1,4-butanedithiol, 1,5-pentanedithiol, and 1,6-hexanedithiol on silver surface has been investigated by surface-enhanced Raman spectroscopy. It has been found that the conformations of the adsorbates were mainly affected by steric interaction of the adsorbates with the surface. As the alkyl chain length separating the thiol groups increased, surface stacking efficiency became increasingly important in determining conformation of the adsorbate on the surface.
