An absorption ‘edge’ is the abrupt increase in absorbance that occurs when the energy of the incident light (typically light in the X-ray region of the electromagnetic spectrum) exceeds the binding energy of a core electron. X-ray absorption spectroscopy uses the structured absorption on the high-energy side of an absorption edge to determine the local structure of the X-ray-absorbing atom.
