Measurement method of
X-ray absorption analysis in which the fine structure of the adsorption spectrum in the range
\(\pu{30 eV}\) below to
\(\pu{50 eV}\) above the absorption edge is used to measure parameters describing the chemical state, coordination environment, and local geometry distortion for the X-ray absorbing atom.
Notes: - The method uses synchrotron radiation.
- The wavelength of the emitted photoelectrons is longer than the interatomic distances between the absorbing atom and its nearest neighbours.
