EXAFS (Extended X-ray Absorption Fine Structure)

Extended X-ray Absorption Fine Structure (EXAFS) is a sophisticated technique used to study the local environment of atoms in materials. When X-rays are directed at a sample, some are absorbed, causing inner shell electrons to be ejected. The resulting absorption spectrum provides detailed information about the distances and types of neighboring atoms around the absorbing atom. By analyzing these patterns, researchers can gain insights into the material's structure, bonding, and electronic properties, making EXAFS valuable in fields like chemistry, materials science, and biology for understanding complex systems at the atomic level.
