Catalytic Carbon K Edge X-ray Absorption Spectroscopy: Multilayer Mirror Detection System
Daniel A. Fischer, S Sambasivan, A Kuperman, Y Platonov, J L. Wood
Fluorescence yield x-ray absorption spectroscopy of the low Z elements C, N, O, and F is a powerful tool for understanding the local structure and chemistry of diverse materials, even in the presence of reactive atmospheres. This technique uses tunable monochromatic synchrotron radiation in the soft x-ray region to excite inner shell electrons to unoccupied molecular orbitals, providing both elemental tunability and chemical state sensitivity in complex systems (also called, Near Edge X-ray Absorption Fine Structure, NEXAFS). By monitoring carbon fluorescence yield during soft x-ray absorption, a photon-in photon-out spectroscopy has been developed for in-situ single crystal surface science experiments involving chemisorption, displacement, and dehydrogenation.
