X-ray Absorption Spectroscopy

2013
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 Metalloproteins

2014
Metalloproteins 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 ...

X-ray Absorption Spectroscopy of the Actinides

2007
The 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, 2023
Theoretical 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 ...
