X射线吸收光谱中的边缘表现出精细结构，称为XANES（X射线吸收近边缘结构）和EXAFS（扩展X射线吸收精细结构）。EXAFS关于原子间距离、配位数和有序度的测定的信息内容在本文的第一部分中给出[趋势分析]。化学成分：11（1992）218]。第二部分讨论了吸收原子边缘附近的精细结构，即XANES区域，它包含了吸收原子的电子结构和几何结构的信息。
The edges in X-ray absorption spectra exhibit fine structures designated as XANES (X-ray absorption near edge structure) and EXAFS (extended X-ray absorption fine structure). The information content of EXAFS with regard to interatomic distances, coordination number, and the determination of degrees of order was presented in the first part of this article [Trends Anal. Chem., 11 (1 992) 218]. The second part deals with the fine structures near to the edge, the XANES region, which contains information about the electronic and the geometric structure of the absorbing atom.
