This comprehensive treatment of the fundamental principles and applications of NEXAFS spectroscopy develops all concepts from an elementary level, presenting a unified picture of the latest theoretical and experimental results. The power of this technique is demonstrated, in particular, in the application to low-Z molecules bonded to surfaces, systems of special interest in surface chemistry, where NEXAFS reveals the electronic and structural properties of the molecules. While researchers and students without extensive prior knowledge of X-ray absorption spectroscopy are catered for by the systematic presentation of the underlying concept, practicing spectroscopists will find here details of state-of-the-art instrumentation in analysis techniques, and results, along with tabulated information about the various molecular adsorption systems that have already been studied by NEXAFS.In polyatomic molecules, the molecular orbitals involve atomic overlap, which is generally more extended, but the ... For homonuclear molecules, orbitals are given a second label g (gerade) or u (ungerade) indicating the inversion ... 3.1.
