X-Ray Absorption Spectroscopy of Metalloproteins
2014Metalloproteins are enormously important in biology. While a variety of techniques exist for studying metals in biology, X-ray absorption spectroscopy is particularly useful in that it can determine the local electronic and physical structure around the metal center, and is one of the few avenues for studying "spectroscopically silent" metal ions like ...

Abstract This chapter reviews recent progress in applications of X-ray absorption spectroscopy to the study of clays and clay minerals. Scanning transmission X-ray microscopy (STXM) has been shown to be a versatile tool, useful for the study of cation exchange in smectite, dissolution reactions in wet samples and to determine the amount of ...

X-ray Absorption Spectroscopy of the Actinides
2007The recent availability of synchrotron radiation has revolutionized actinide chemistry. This is particularly true in environmental studies, where heterogeneous samples add to the already multifaceted chemistry exhibited by these ions. Environmental samples are often inhomogeneous, chemically diverse, and amorphous or poorly crystalline. Even surrogates

Signatures of diradicals in x-ray absorption spectroscopy
The Journal of Chemical Physics, 2023Theoretical simulations are critical to analyze and interpret the x-ray absorption spectrum of transient open-shell species. In this work, we propose a model of the many-body core-excited states of symmetric diradicals. We apply this model to analyze the carbon K-edge transitions of o-, m-, and p-benzyne, three organic diradicals with diverse and ...

X-ray absorption spectroscopy (XAS) involves the excitation of core electrons to bound states localized on the photoabsorber and the eventual excitation of the photoelectron to the continuum. The resulting spectra are typically divided into two regions: (1) the edge region which provides electronic structure information and (2) the extended X-ray ...

X-ray absorption spectroscopy has been one of the most used tools to study structures and structural changes in chemistry, especially since synchrotron light facilities became available almost 50 years ago. This chapter will give a theoretical background to X-ray absorption spectroscopy, and methods and applications in inorganic and metalorganic ...

X-Ray Absorption Spectroscopy of Metalloproteins
2018X-ray absorption spectroscopy (XAS) has been widely used as a powerful local structural tool for studying the metal binding sites in metalloproteins, owing to its element specificity, chemical sensitivity, and minimum requirement for sample preparation.

X-ray absorption spectroscopic techniques have emerged over the past 50 years to offer important insights into the coordination environments, valence, and spin states in a wide variety of materials. They are particularly relevant to research on energy storage materials where even the most subtle changes in metal oxidation state and local atomic ...

Introduction to X-Ray Absorption Spectroscopy
2014X-ray Absorption Fine Structure (XAFS) contains original information on the local properties of materials. After a general introduction to the X-ray absorption process, the attention is here focussed on the extended fine structure (EXAFS). The main approximations that lead to a relatively simple and effective interpretation of EXAFS spectra are ...
