Abstract

Local structure around the sulfur atoms of vacuum-deposited dihexyldisulfide on Ag(100) was studied by use of S K-edge X-ray absorption fine structure (XAFS) spectroscopy. It turned out that the S-S bond of disulfide is cleaved on adsorption and hexanethiolate monolayers are formed on Ag(100). Surface XAFS analysis revealed that S of the thiolate is located on the fourfold hollow site of Ag(100) without reconstruction. The bond distances, R(S-Ag) and R(S-C) are determined to be 2.53±0.02 and 1.81±0.04 Å, respectively.
