XAS

X-ray Absorption Spectroscopy (XAS) is a technique used to study the structure and environment of specific elements within a material. When X-rays are directed at a sample, they are absorbed differently depending on the element and how its atoms are arranged. By analyzing these absorption patterns, scientists can determine details such as the oxidation state, local geometric structure, and neighboring atoms of the element. XAS is valuable in fields like chemistry, material science, and biology for understanding materials at an atomic level without damaging them.
