Analysis of the energy absorbed across a spectrum of x-ray energies/wavelengths to determine the chemical structure and electronic states of the absorbing medium.
Entry Term(s)
NEXAFS Spectroscopy
Near Edge X-Ray Absorption Fine Structure Spectroscopy
Near-Edge X-Ray Absorption Fine Structure Spectroscopy
Analysis of the energy absorbed across a spectrum of x-ray energies/wavelengths to determine the chemical structure and electronic states of the absorbing medium.
Analysis of the oscillations observed in an x-ray absorption spectrum that begin just above the absorption edge (i.e. the point on the spectrum where the amount of x-ray absorption suddenly increases) to determine or evaluate the chemical structure of the absorbing surface.
