X-ray absorption near edge structure (XANES), also known as near edge X-ray absorption fine structure (NEXAFS), is a type of absorption spectroscopy that indicates the features in the X-ray absorption spectra (XAS) of condensed matter due to the photoabsorption cross section for electronic transitions from an atomic core level to final states in the energy region of 50–100 eV above the selected atomic core level ionization energy, where the wavelength of the photoelectron is larger than the interatomic distance between the absorbing atom and its first neighbour atoms.

| - Die Röntgen-Nahkanten-Absorptions-Spektroskopie, englisch near-edge x-ray absorption fine structure oder X-ray absorption near-edge structure spectroscopy, kurz NEXAFS- oder XANES-Spektroskopie, ist ein zur Röntgenabsorptionsspektroskopie gehörendes Spektroskopie-Verfahren zur Untersuchung von Festkörperoberflächen. Es erfasst die unbesetzten Elektronen-Zustände und kann die Häufigkeit sowie die räumliche Lage von Atomen oder Molekülen auf der Oberfläche untersuchen. (de)
- XANES, qui signifie X-ray Absorption Near Edge Structure (soit en français Spectroscopie de structure près du front d'absorption de rayons X) est une méthode d'analyse de spectrométrie d'absorption des rayons X, qui utilise le rayonnement synchrotron. Elle est généralement couplée avec la technique EXAFS (Extended X-Ray Absorption Fine Structure) pour obtenir des informations sur le voisinage de ces composés. La différence principale entre ces deux techniques concerne l'échelle d'énergie considérée autour du front d'absorption. Le XANES est également appelé NEXAFS (Near Edge X-ray Absorption Fine Structure) dans certaines disciplines (science des surfaces par exemple). (fr)

- La spettroscopia XANES (dall'inglese X-ray absorption near edge structure) è un tipo di spettroscopia XAS. Lo spettro XAS infatti viene convenzionalmente diviso nella regione XANES (X-ray Absorption Near Edge Structure), da prima della soglia a circa 50 eV dopo la soglia, e nella regione EXAFS (Extended X-ray Absorption Fine Structure), che si estende fino alla fine dello spettro.
