Herein, the O K-edge X-ray absorption spectroscopy (XAS) profile of an aqueous acetonitrile solution presented a distinct sharp peak not commonly observed in the corresponding profile of liquid water.

X-ray spectroscopy measurements that previously needed to be done at a synchrotron facility could become available to a broader audience thanks to a new tabletop system (Anal. Chem. 2022, DOI: 10.1021 ...

What is X-ray Absorption Spectroscopy (XAS)? X-ray Absorption Spectroscopy (XAS) is a powerful analytical technique that probes the local atomic and electronic structure of materials by measuring the ...

X-ray spectroscopy techniques (e.g. X-ray emission spectroscopy, X-ray absorption spectroscopy, etc.) are used in a variety of applications including in material science, astronomy, and biomedical.

The many-body interaction of charges (electrons) and nuclei (phonons) plays a critical role in determining the properties and functionalities of molecules and solids. The exact correlated motion of ...

X-ray spectroscopic techniques rely on the element-specificity of inner-shell photoexcitation/ionization to probe electronic densities with atomic-site precision. The ...

XES is an element-specific method primarily used to analyze the partially occupied electronic structure of materials. The technique is one of the photon-in-photon-out spectroscopies in which an ...

This sharp jump in absorption is called the absorption edge. By tracking how X-ray absorption changes before, during and after this edge, researchers can watch the chemistry of a specific element ...
