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

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 ...

What is Scanning Transmission X-ray Microscopy (STXM)? Scanning Transmission X-ray Microscopy (STXM) is a powerful imaging technique that combines the principles of X-ray spectroscopy and microscopy ...

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.
