Wavelengths of the characteristic X-ray are principally determined by the binding energy of orbitals peculiar to the analyte element, which is a principle of X-ray fluorescence spectroscopy.Wagatsuma, KazuakiTohoku University
X-ray absorption spectroscopy (XAS) has become an indispensable tool to in situ investigate dynamic natures of electrocatalysts but still suffers from limited energy resolution, leading to significant electronic transitions poorly resolved. Herein, we highlight advanced X-ray spectroscopies beyond ...
X-Ray Photoelectron Spectroscopy Applications M.H. Engelhard, ... Y. Du, in Encyclopedia of Spectroscopy and Spectrometry (Third Edition), 2017 Abstract X-ray photoelectron spectroscopy (XPS) is, in principle, based on a particularly simple process. Electrons within a sample absorb photons of a...
X-ray photoelectron spectroscopy (XPS) is widely used to identify chemical species at a surface through the observation of peak positions and peak shapes. It is less widely recognized that intensities in XPS spectra can also be used to obtain information on the chemical composition of the surface...
X-Ray Spectroscopy Although a vacancy produced by ionization in any given atomic shell (Figure 2) may potentially be filled by electrons from a number of transition levels (as dictated by the rules of quantum theory), in practice, most of these possible transitions are statistically rare and th...

In this review, the effect of chemical bonding in x-ray spectroscopy is described. It is evident that the state of chemical combination of an element may have a significant influence on both the wavelength and intensity of X-ray lines. The main peak of K emission spectra and K absorption ...
Here, we demonstrate a first x-ray absorption spectroscopy proof-of-principle experiment using an inverse Compton x-ray source with a flux of >10photons/s in <5% bandwidth. We measured x-ray absorption near edge structure and extended x-ray absorption fine structure at the silver K-edge (~...

the decay of nuclear polaritons could lead to extremely narrow-band, non-classical light sources in the X-ray range, and open the way for new applications in high-precision spectroscopy." At the same time, the experiment is a further step towards establishing quantum optics in the X-ray ...
