X-ray Absorption Spectroscopy

open access: yes, 2010
X-ray absorption spectroscopy (XAS) has been a powerful tool to probe physical and chemical structure for an atom, which includes two regions, X-ray absorption near edge structure (XANES) and extended X-ray absorption fine structure (EXAFS). The main object of this chapter is to give the readers a brief idea about XAS and its application, alone or ...
