X-Ray Spectra and Chemical Binding


Book Description

In the 12 years that have passed since the publication of Riintgenspektren und chemische Bindung, the original German work on which· this text is based, several aspects of high-resolution X-ray spectroscopy have devel oped rapidly. After accepting the suggestion of Dr. R.D. Deslattes that a translation should be prepared, we thoroughly revised the book in order to include these recent developments in theory, equipment and applications. The latest reSearch results and publications that had appeared by 1987/1988 have been taken into account in the analysis. However, as the general treatment of the German edition is still valid today, the organization of the contents did -not have to be modified. The present status of the field is adequately described just by the addition of supplementary material in the English edition. We have merely rearranged what was previously Chapter 4 into tabular form and placed it as an appendix. This presentation produces greater clarity and increases the ease with which the information can be referred to. We thank Dr. E. Kallne for undertaking the translation. We are grate ful to Dr. R.D. Deslattes and Dr. H. Lotsch for their conscientious and critical checking of the translation. Chapters 3 and 6 were updated by our colleague Dr. H. Sommer, to whom special thanks are due. It is our hope that this transiation and revision will make our text available to a larger section of the scientific community.







X-Ray Absorption and X-Ray Emission Spectroscopy


Book Description

During the last two decades, remarkable and often spectacular progress has been made in the methodological and instrumental aspects of x–ray absorption and emission spectroscopy. This progress includes considerable technological improvements in the design and production of detectors especially with the development and expansion of large-scale synchrotron reactors All this has resulted in improved analytical performance and new applications, as well as in the perspective of a dramatic enhancement in the potential of x–ray based analysis techniques for the near future. This comprehensive two-volume treatise features articles that explain the phenomena and describe examples of X–ray absorption and emission applications in several fields, including chemistry, biochemistry, catalysis, amorphous and liquid systems, synchrotron radiation, and surface phenomena. Contributors explain the underlying theory, how to set up X–ray absorption experiments, and how to analyze the details of the resulting spectra. X-Ray Absorption and X-ray Emission Spectroscopy: Theory and Applications: Combines the theory, instrumentation and applications of x-ray absorption and emission spectroscopies which offer unique diagnostics to study almost any object in the Universe. Is the go-to reference book in the subject for all researchers across multi-disciplines since intense beams from modern sources have revolutionized x-ray science in recent years Is relevant to students, postdocurates and researchers working on x-rays and related synchrotron sources and applications in materials, physics, medicine, environment/geology, and biomedical materials




X-Ray Spectroscopy


Book Description

Rontgen's discovery of X-rays in 1895 launched a subject which became central to the development of modern physics. The verification of many of the predic tions of quantum theory by X-ray spectroscopy in the early part of the twen tieth century stimulated great interest in thi's area, which has subsequently influenced fields as diverse as chemical physics, nuclear physics, and the study of the electronic properties of solids, and led to the development of techniques such as Auger, Raman, and X-ray photoelectron spectroscopy. The improvement of the theoretical understanding of the physics underlying X-ray spectroscopy has been accompanied by advances in experimental techniques, and the subject provides an instructive example of how progress on both these fronts can be mutually beneficial. This book strikes a balance between his torical description, which illustrates this symbiosis, and the discussion of new developments. The application of X-ray spectroscopic methods to the in vestigation of chemical bonding receives special attention, and an up-to-date account is given of the use of extended X-ray absorption fine structure (EXAFS) in determining interatomic distances, which has attracted much attention dur ing the last decade. This monograph is intended to be used as a basic text for a one-year course at postgraduate level, and aims to provide the general background that is es sential to enable the reader to participate fruitfully in the growing research activity in this field.




X-Ray Charge Densities and Chemical Bonding


Book Description

This book deals with the electron density distribution in molecules and solids as obtained experimentally by X-ray diffraction. It is a comprehensive treatment of the methods involved, and the interpretation of the experimental results in terms of chemical bonding and intermolecular interactions. Inorganic and organic solids, as well as metals, are covered in the chapters dealing with specific systems. As a whole, this monograph is especially appealing because of its broad interface with numerous disciplines. Accurate X-ray diffraction intensities contain fundamental information on the charge distribution in crystals, which can be compared directly with theoretical results, and used to derive other physical properties, such as electrostatic moments, the electrostatic potential and lattice energies, which are accessible by spectroscopic and thermodynamic measurements. Consequently, the work will be of great interest to a broad range of crystallographers and physical scientists.

X-ray Absorption Spectroscopy for the Chemical and Materials Sciences


Book Description

A clear-cut introduction to the technique and applications of x-ray absorption spectroscopy X-ray Absorption Spectroscopy is being applied to a widening set of disciplines. Applications started with solid state physics and grew to materials science, chemistry, biochemistry and geology. Now, they cut across engineering materials, environmental science and national heritage — providing very detailed and useful information facilitating understanding and development of materials. This practical guide helps investigators choose the right experiment, carry it out properly and analyze the data to give the best reliable result. It gives readers insights to extract what they need from the world of large-scale experimental facilities like synchrotrons, which seem distant to many laboratory scientists. X-ray Absorption Spectroscopy for the Chemical and Materials Sciences seeks to educate readers about the strengths and limitations of the techniques, including their accessibility. Presented in six sections, it offers chapters that cover: an introduction to X-ray absorption fine structure XAFS; the basis of XAFS; X-ray sources; experimental methods; data analysis and simulation methods; and case studies. A no-nonsense introduction to the technique and applications of x-ray absorption spectroscopy Features Questions to support learning through the book Relevant to all working on synchrotron sources and applications in physics, materials, environment/geology and biomedical materials Four-color representation allows easy interpretation of images and data for the reader X-ray Absorption Spectroscopy for the Chemical and Materials Sciences is aimed at Masters-level and PhD students embarking on X-ray spectroscopy projects as well as scientists in areas of materials characterization.
