Synchrotron Techniques in Interfacial Chemistry covers the structure of the electrode--solution interface and surface films, theory of X-ray scattering at surfaces and interfaces, synchrotron radiation instrumentation, surface X-ray diffraction, X-ray reflectivity, X-ray absorption spectroscopy (EXAFS and XANES), standing wave techniques, and IR spectroscopy. The use of each technique in the study of electrochemical problems is illustrated.
