X-ray Absorption Spectroscopy

open access: yesNature Reviews Methods Primers
X-ray absorption spectroscopy (XAS) can be used to analyze electronic structures and local structures around the metal ion in metal complexes. XAS is usually divided into two regions: X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS). XANES mainly reflects the electronic structures, and EXAFS contains the

Laser plasma x-ray source for ultrafast time-resolved x-ray absorption spectroscopy

open access: yesStructural Dynamics, 2015
We describe a laser-driven x-ray plasma source designed for ultrafast x-ray absorption spectroscopy. The source is comprised of a 1 kHz, 20 W, femtosecond pulsed infrared laser and a water target.

X-Ray Absorption Spectroscopy

open access: yesActa Physica Polonica A, 1994
X-ray absorption spectroscopy, today widely used as a tool for structural investigations, is described. Theoretically it is shown that above an absorption edge the absorption coefficient is well approximated by a sum of terms, each one describing a particular path followed by the photoelectron outgoing from the atom.
