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 ...

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 photoelectron spectroscopy is based on the same principle as all photoelectron spectroscopy methods. If a molecule or material is irradiated with light of a known energy above the ionization ...

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 ...

A synchrotron is a circular particle accelerator. Charged particles (electrons) are accelerated through many magnets in the device until they exceed the speed of light. These particles produce a ...

With the advancement of laser technology, ultrashort pulsating lasers give a new technological technique for highly precise spectroscopic measurement. To precisely monitor wavelengths, the optical ...
