X-ray Absorption Spectroscopy (XAS) is a powerful analytical technique used to study the electronic and structural properties of materials at the atomic level. It involves the measurement of the absorption of X-rays by a sample as a function of energy. The technique provides information about the oxidation state, coordination geometry, and local environment of specific elements within a material.
