XANES

XANES (X-ray Absorption Near Edge Structure) je tehnika spektroskopije rendgenskim zračenjem na sinkrotronu koja mjeri elektronsku i geometrijsku strukturu oko određenog atoma analizirajući spektar apsorpcije rendgenskog zračenja unutar otprilike 50 eV od ruba apsorpcije. Razvijen od strane Leea i Pendryja 1975. godine, XANES je komplementaran EXAFS-u i otkriva valentno stanje, lokalnu simetriju i strukturu nepopunjenih orbitala kroz značajke i rezonancije blizu praga.
