The K X-ray absorption spectra of Fe, Fe2O3, and Fe3O4 were measured at liquid nitrogen and boiling water temperatures. The results demonstrate a temperature dependence in the fine structure of the iron spectra, but none was observed for the oxides. These results are compared with the Kronig theory for extended fine structure, and the possibility that thermal vibrations are responsible in part for the temperature dependence is proposed. Further experiments are suggested to test this hypothesis.
