High-Resolution XAS/XES

<p>Photon-in-photon-out core level spectroscopy is an emerging approach to characterize the electronic structure of catalysts and enzymes and it is either installed or planned for intense synchrotron beam lines and X-ray free electron lasers. This type of spectroscopy requires high-energy resolution spectroscopy not only for the incoming X-ray beam but also in most applications for the detection of the outgoing photons. Thus the use of high-resolution X-ray crystal spectrometers whose resolving power ΔE/E is typically about 10–4 is mandatory.</p><p>High-Resolution XAS/XES: Analyzing Electronic Structures of Catalysts covers the latest developments in X-ray light sources detectors crystal spectrometers and photon-in-photon-out core level spectroscopy techniques. It also addresses photon-in-photon-out core level spectroscopy applications for the study of catalytic systems highlighting hard X-ray measurements primarily due to probe high penetration enabling <i>in situ</i> studies. </p><p>This first-of-its-kind book:</p><ul> <li>Discusses high-resolution X-ray emission spectroscopy (XES) and X-ray absorption spectroscopy (XAS) in terms of time-resolved and surface enhancement</li> <li>Supplies an understanding of catalytic reactivity essential for capitalizing on core level X-ray spectroscopy at fourth-generation light sources (XFELs)</li> <li>Describes all spectrometers developed to perform core level X-ray spectroscopy considering the advantages and disadvantages of each</li> <li>Details methods to elucidate aspects of catalysts under working conditions such as active sites and molecule adsorption</li> <li>Introduces theoretical calculations of spectra and explores biological as well as heterogeneous catalysts</li> </ul><p>Complete with guidelines and warnings for the use of this type of spectroscopy <b>High-Resolution XAS/XES: Analyzing Electronic Structures of Catalysts </b>provides a comprehensive overview of the current state of this exciting field.</p>
