摘要：

The adsorption geometry of S in the c(2 x 2) structure on Rh(100) has been determined using surface extended X-ray absorption fine structure (SEXAFS. It is found that S adsorbs in the symmetrical four-fold hollow site with an S-Rh bond length of 2.35 +/- 0.04 Angstrom. This geometry is consistent with S adsorption on the neighbouring (100) surfaces of Ni, Cu and Pd.
