X-ray Absorption Spectroscopy X-ray absorption spectroscopy (XAS) techniques probe short- and medium-range order‚ yielding information on bond lengths‚ coordination numbers‚ local coordination geometry and the oxidation state of atoms for a wide range of solid and liquid systems. XAS experiments require an intense‚ tunable photon source only available at synchrotrons. Features • medium and high energy (from atomic number Z=20 upwards) XAS‚ XANES (x-ray absorption near-edge structure)
