Structure determination of Rh(100)-c(2 × 2)-S using the surface extended X-ray absorption fine structure technique

The adsorption geometry of S in the c(2 × 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 A ̊ . This geometry is consistent with S...

Description
Summary:The adsorption geometry of S in the c(2 × 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 A ̊ . This geometry is consistent with S adsorption on the neighbouring (100) surfaces of Ni, Cu and Pd.
