Analysis of Compounds Containing Multiple Valence and/or Coordination Using X-Ray Absorption Spectra
Interpretation of x-ray absorption spectra when an element exists in a compound in more than one valence and/or coordination is difficult. The observed spectrum is a statistical average of the spectra of all species present. This combination of spectra modifies, and in some cases wipes out, absorption peaks. In order to analyze such compounds, it is first necessary to obtain reference spectra of species potentially present. A regression analysis is then performed an the spectra in order to simulate the unknown spectrum. This paper describes the details of this mathematical analysis of absorption data and demonstrates the solution of some interesting structural problems.
