<strong>What</strong> <strong>is</strong> X-ray absorption fine structures (XAFS) <br />
• As core electron <strong>is</strong> excited with hv the threshold<br />
(E o ), it <strong>is</strong> excited to a final state defined by the<br />
chemical environment, which modulates the<br />
absorption coefficient relative to that of a free<br />
atom. Th<strong>is</strong> modulation <strong>is</strong> known the XAFS,<br />
• XAFS contains all the information about the local<br />
structure and bonding of the absorbing atom<br />
• XAFS study requires a tunable X-ray source –<br />
<strong>synchrotron</strong> <strong>radiation</strong><br />
