Core-Level Spectroscopy

Core-level spectroscopy is a technique used by scientists to study the inner electrons of atoms within materials. When these electrons absorb specific energies of light or particles, they can be ejected or excited, revealing information about the element's identity and its chemical environment. This method helps researchers understand material properties, chemical states, and electronic structure at a detailed level, which is crucial in fields like chemistry, materials science, and physics. Essentially, it acts as a microscopic “fingerprint” for atoms, providing insights into how atoms are arranged and behave inside different substances.
