ABSTRACT
You may be wondering how this chapter ts in with Section 1.6.4 of Chapter 1, which spends a page on curve tting to theoretical standards, and with Part III, which spends ve chapters on it. The answer is that in this chapter we’ll examine a bit more closely the theoretical underpinnings of theoretical standards and how they are used. Although the primary focus is on EXAFS, the distinction between EXAFS and XANES is not sharp, so we’ll touch on some aspects of XANES as well. In the nal section of the chapter, we will also provide an introduction to strategies for modeling, which in turn provides a framework for the material in Part III.
