Advances in long-wavelength native phasing at X-ray free-electron lasers

Karol Nass, R.K. Cheng, Laura Vera, A. Mozzanica et autres

Long-wavelength pulses from the Swiss X-ray free-electron laser (XFEL) have been used for de novo protein structure determination by native single-wavelength anomalous diffraction (native-SAD) phasing of serial femtosecond crystallography (SFX) data. In this work, sensitive anomalous data-quality indicators and model proteins were …

Taking a snapshot of the triplet excited state of an OLED organometallic luminophore using X-rays

Grigory Yu. Smolentsev, Christopher Jackson Milne, Alexander Alexandrovich Guda, Kristoffer Haldrup et autres

OLED technology beyond small or expensive devices requires light-emitters, luminophores, based on earth-abundant elements. Understanding and experimental verification of charge transfer in luminophores are needed for this development. An organometallic multicore Cu complex comprising Cu-C and Cu-P bonds represents an underexplored type …

Toward time-resolved laser T-jump/X-ray probe spectroscopy in aqueous solutions

Oliviero Cannelli, Camila Bacellar, Rebecca A. Ingle, Rok Bohinc et autres

Most chemical and biochemical reactions in nature and in industrial processes are driven by thermal effects that bring the reactants above the energy barrier for reaction. In aqueous solutions, this process can also be triggered by the laser driven temperature jump (T-jump) …

Tracking multiple components of a nuclear wavepacket in photoexcited Cu(I)-phenanthroline complex using ultrafast X-ray spectroscopy

Tetsuo Katayama, Thomas Northey, Wojciech Gawełda, Christopher Jackson Milne et autres

Abstract Disentangling the strong interplay between electronic and nuclear degrees of freedom is essential to achieve a full understanding of excited state processes during ultrafast nonadiabatic chemical reactions. However, the complexity of multi-dimensional potential energy surfaces means that this remains challenging. The …

Nonlinear XUV-optical transient grating spectroscopy at the Si L2,3–edge

Rok Bohinc, Georgios Pamfilidis, Julien Réhault, Peter Radi et autres

Time-resolved transient grating (TG) spectroscopy facilitates detailed studies of electron dynamics and transport phenomena by means of a periodic excitation of matter with coherent ultrashort light pulses. Several current and next generation free-electron laser (FEL) facilities provide fully coherent pulses with few …

Distribution of aluminum over different T-sites in ferrierite zeolites studied with aluminum valence to core X-ray emission spectroscopy

Rok Bohinc, Joanna Hoszowska, J.‐Cl. Dousse, Wojciech Błachucki et autres

shoulder in the Al emission spectra can be linked to a predominant occupation of the T3 site by a single aluminum atom. This study thus suggests that valence to core X-ray emission spectroscopy can be applied to help determine the occupation of …

Electronic Structure of Third-Row Elements in Different Local Symmetries Studied by Valence-to-Core X-ray Emission Spectroscopy

Marko Petrič, Rok Bohinc, K. Bučar, S. Nowak et autres

The electronic structure of phosphorus, sulfur, and chlorine in compounds with T d and C 3 v local symmetries was studied with high-resolution Kβ X-ray emission spectroscopy (XES) in the tender X-ray range. Measured spectra are compared to the results of ab …

Structural and dynamical properties of chlorinated hydrocarbons studied with resonant inelastic x-ray scattering

Rok Bohinc, M. Žitnik, K. Bučar, M. Kavčič et autres

We present a theoretical and experimental study of resonant inelastic x-ray scattering on a large group of chlorinated hydrocarbons: CH3Cl, CH2Cl2, CHCl3, CCl4, CH3CH2Cl, ClCH2CH2Cl, CH3CHCl2, CH3CCl3, C2H2Cl2-iso, C2H2Cl2-cis, C2H2Cl2-trans, and C6H5Cl. Differences in structural and dynamical properties of the molecules generated …

Electron dynamics in the core-excited CS2 molecule revealed through resonant inelastic x-ray scattering spectroscopy

T. Marchenko, S. Carniato, L. Journel, R. Guillemin et autres

We present an experimental and theoretical study of resonant inelastic x-ray scattering (RIXS) in the CS 2 molecule near the S 1s edge. We show that localization of the S 1s core-hole occurs in CS 2 during the RIXS process due to …

Resonant X-ray Scattering of carbonyl sulfide at the sulfur K edge

L. Journel, T. Marchenko, R. Guillemin, Elie Kawerk et autres

New results on free OCS molecules have been obtained using Resonant X-ray Inelastic Scattering spectroscopy. A deconvolution algorithm has been applied to improve the energy resolution spectra of which we can extract detailed information on nuclear dynamics in the system.
