Abstract
Despite the abundance of available experimental techniques, the X-ray absorption spectroscopy often remains the only acceptable means for solving a number of problems: studying X-ray amorphous substances, determining the phase composition at a lower concentration limit for impurity samples, determining the valence state of a chemical element in the case of a low content thereof in the sample (mass percent quota). The present review reports the theory and examples of successful applying the methods of EXAFS and XANES to solve complicated problems.
