Information
has glosseng: X-ray Absorption Spectroscopy (XAS) includes both Extended X-Ray Absorption Fine Structure (EXAFS) and X-ray Absorption Near Edge Structure (XANES). XAS is the measurement of the x-ray absorption coefficient ( \mu (E) in the equations below) of a material as a function of energy. X-rays of a narrow energy resolution are shone on the sample and the incident and transmitted x-ray intensity is recorded as the incident x-ray energy is incremented. The number of x-rays that are transmitted through a sample (It) is equal to the number of x-rays shone on the sample (I0) multiplied by a decreasing exponential that depends of the type of atoms in the sample, the absorption coefficient \mu, and the thickness of the sample x.

Meaning
German
has glossdeu: EXAFS, vom Englischen , ist ein Verfahren der Röntgenabsorptionsspektroskopie, mit dessen Hilfe die Art, Anzahl und Entfernung von Nachbaratomen (Liganden) eines bestimmten chemischen Elements in Molekülen, einer Flüssigkeit oder einem Festkörper bestimmt werden kann. Wird die Methode zur Untersuchung von Molekülen an Oberflächen verwendet, wird sie auch als SEXAFS (engl. ) bezeichnet.

French
has glossfra: La spectroscopie EXAFS (Extended X-Ray Absorption Fine Structure) est une technique danalyse de spectrométrie dabsorption des rayons X utilisant principalement le rayonnement synchrotron. Elle apporte des informations sur lenvironnement atomique dun élément donné. Contrairement à des méthodes telles que la diffraction de rayons X (XRD) qui nécessitent une structure régulière du matériau, la spectroscopie EXAFS est applicable dans tout type de milieu : solide, liquide, gaz et interfaces. Elle est généralement couplée avec la technique XANES (X-Ray Absorption Near Edge Structure).

Italian
has glossita: La spettroscopia EXAFS (dall'inglese extended X-ray absorption fine 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 60-100 eV dopo la soglia, e nella regione EXAFS (Extended X-ray Absorption Fine Structure), che si estende fino alla fine dello spettro.

has glossnld: EXAFS is een afkorting voor Extended X-ray Absorption Fine Structure en is een techniek waarmee de structuur van de onmiddellijke omgeving van een bepaald atoom bestudeerd kan worden.
