X-ray absorption spectroscopy

X-ray absorption spectroscopy


X-ray absorption fine structure (XAFS) is a powerful spectroscopic technique that generally requires application of synchrotron X-ray radiation. It provides information on the physical and chemical properties of matter at the atomic scale. XAFS is an element-specific technique which allows to selectively probe the local structure around the absorbing atom. XAFS can be applied to the materials in both solid, liquid and even gas phase. Unlike X-ray diffraction, the method does not require long range order in the samples and can be used to study the structure of nanomaterials, small molecules, enzymes and proteins, and many others. The extended X-ray absorption fine structure (EXAFS) provides the radial distribution function, so interatomic distances and coordination numbers can be extracted. At the same time, X-ray absorption near-edge structure (XANES) is also sensitive to the electronic structure, oxidation state, bond angles (3D geometry). 

Our group has a big experience in experimental applications and theoretical analysis of XAFS. The members of our team have performed a huge number of experiments at the world leading synchrotron radiation sources, such as ESRF and Soleil (France), DORIS, ANKA, DESY and BESSY (Germany), SLS (Switzerland), MAX-IV (Sweden), ELETTRA (Italy), Kurchatov Institute (Russia). Moreover, we have a unique laboratory X-ray absorption spectrometer manufactured by Rigaku, which has no analogues in Russia and Europe. 

For theoretical analysis of EXAFS, we use standard Fourier-analysis (software: Athena, Artemis, Wiper). The analysis of XANES is an independent and very complicated field, in which our group have a big expertise. In particular, we have developed a FitIt code, which allows fitting the experimental spectra using multidimensional interpolation approach [1,2]. Recently, we made a significant improvement in the computational performance (up to 40 times speedup!) of the famous FDMNES code for XANES calculations [3].
