Journal ArticleDOI
A Von Hamos X-Ray Spectrometer Based on a Segmented-Type Diffraction Crystal for Single-Shot X-Ray Emission Spectroscopy and Time-Resolved Resonant Inelastic X-Ray Scattering Studies
Jakub Szlachetko,Maarten Nachtegaal,E. De Boni,M. Willimann,Olga V. Safonova,Jacinto Sá,Grigory Smolentsev,M. Szlachetko,J. A. van Bokhoven,J.-Cl. Dousse,Joanna Hoszowska,Yves Kayser,Paweł P. Jagodziński,Anna Bergamaschi,Bernd Schmitt,Christian David,A. Lücke +16 more
TL;DR: The design and performance of a wavelength-dispersive type spectrometer based on the von Hamos geometry equipped with a segmented-type crystal for x-ray diffraction and an energy resolution in the order of 0.25 eV and 1 eV is reported.
Journal ArticleDOI
Optimized Finite Difference Method for the Full-Potential XANES Simulations: Application to Molecular Adsorption Geometries in MOFs and Metal–Ligand Intersystem Crossing Transients
Sergey A. Guda,Alexander A. Guda,Mikhail A. Soldatov,Kirill A. Lomachenko,Aram L. Bugaev,Carlo Lamberti,Wojciech Gawelda,Christian Bressler,Christian Bressler,Grigory Smolentsev,Alexander V. Soldatov,Yves Joly,Yves Joly +12 more
TL;DR: Ni K-edge XANES simulations performed by the accelerated version of the code allowed analyzing the coordination geometry of CO and NO on the Ni active sites in CPO-27-Ni MOF, and the X-ray absorption spectrum for the intermediate triplet state with expected 100 fs lifetime was theoretically predicted.
Journal ArticleDOI

Moser,Ursula Rothlisberger,Grigory Smolentsev,Joël Teuscher,Jeroen A. van Bokhoven,Jeroen A. van Bokhoven,Oliver S. Wenger +22 more
TL;DR: Important new insights into each of the elementary steps of charge transfer in liquids and nanoparticles, obtained from state-of-the-art ultrafast spectroscopy and/or theoretical methods, are summarized in this review.
Journal ArticleDOI
X-ray emission spectroscopy to study ligand valence orbitals in Mn coordination complexes
Grigory Smolentsev,Alexander V. Soldatov,Johannes Messinger,Kathrin Merz,Thomas Weyhermüller,Uwe Bergmann,Yulia Pushkar,Junko Yano,Vittal K. Yachandra,Pieter Glatzel +9 more
TL;DR: A spectroscopic method is discussed to determine the character of chemical bonding and for the identification of metal ligands in coordination and bioinorganic chemistry based on the analysis of satellite lines in X-ray emission spectra that arise from transitions between valence orbitals and the metal ion 1s level (valence-to-core XES).
Journal ArticleDOI
Palladium versus Platinum: The Metal in the Catalytic Center of a Molecular Photocatalyst Determines the Mechanism of the Hydrogen Production with Visible Light
Michael G. Pfeffer,Bernhard Schäfer,Grigory Smolentsev,Grigory Smolentsev,Jens Uhlig,Elena Nazarenko,Julien Guthmuller,Christian Kuhnt,Maria Wächtler,Benjamin Dietzek,Villy Sundström,Sven Rau +11 more
TL;DR: Investigating the nature of the catalytically active metal center in a (N^N)MCl2 (M=Pd or Pt) coordination sphere has a significant impact on the mechanism of the hydrogen formation, and for Pt a fundamentally different catalytic mechanism without the involvement of colloids is confirmed.
