X-ray absorption near edge structure (XANES), also known as near edge X-ray absorption fine structure (NEXAFS), is a type of absorption spectroscopy

XANES is strongly sensitive to oxidation state and coordination chemistry of the absorbing atom, while EXAFS is used to determine the bond length, coordination ...

與X光吸收光譜相關的技術，有稱之為X光吸收細微結構（X-ray Absorption Fine Structure, XAFS），或延伸X光吸收細微結構（Extended X-ray Absorption Fine Structure, EXAFS）。

2023年1月29日 — The difference between XANES and EXAFS is loosely defined as space difference in terms of which regime they represent in a XAS spectrum.
