Autor: Ph, Wernet, T, Leitner, I, Josefsson, T, Mazza, P S, Miedema, H, Schröder, M, Beye, K, Kunnus, S, Schreck, P, Radcliffe, S, Düsterer, M, Meyer, M, Odelius, A, Föhlisch

Publikováno v: The Journal of chemical physics. 146(21)

We prove the hitherto hypothesized sequential dissociation of Fe(CO)5 in the gas phase upon photoexcitation at 266 nm via a singlet pathway with time-resolved valence and core-level photoelectron spectroscopy with an x-ray free-electron laser. Valenc

We analyze the effects of covalent interactions in Ni 2p3d resonant inelastic X ray scattering RIXS spectra from aqueous Ni2 ions and find that the relative RIXS intensities of ligand to metal charge transfer final states with respect to the ligand f

Probing the Hofmeister Effect with Ultrafast Core–Hole Spectroscopy

Autor: Alexander Föhlisch, Zhong Yin, Ivan Rajkovic, Simone Techert, W. Quewedo, Katharina Kubicek, Annette Pietzsch, Ph. Wernet

Publikováno v: Journal of Physical Chemistry B
The journal of physical chemistry / B 118(31), 9398-9403 (2014). doi:10.1021/jp504577a

In the current work, X-ray emission spectra of aqueous solutions of different inorganic salts within the Hofmeister series are presented. The results reflect the direct interaction of the ions with the water molecules and therefore, reveal general pr

Time-resolved X-ray absorption spectroscopy of infrared-laser-induced temperature jumps in liquid water

Autor: Thomas Elsaesser, Erik T. J. Nibbering, Wolfgang Eberhardt, Ph. Wernet, Christian Weniger, K. Godehusen, G. Gavrila

Publikováno v: Applied Physics A. 96:11-18

A time resolved X ray absorption study of the structural dynamics of liquid water on a picosecond timescale is presented. We apply femtosecond midinfrared pulses to resonantly excite the intramolecular O H stretching band of liquid water and monitor

Ultrafast temperature jump in liquid water studied by a novel infrared pump-x-ray probe technique

Autor: Ph. Wernet, Thomas Elsaesser, Wolfgang Eberhardt, Erik T. J. Nibbering, G. Gavrila, Christian Weniger, K. Godehusen

Publikováno v: Applied Physics A. 92:511-516

We report the first infrared pump-x-ray probe study of the structural dynamics of liquid water. Femtosecond infrared excitation via the O–H stretching band induces an ultrafast temperature jump that gives rise to changes in the hydrogen bond networ

Publikováno v: Journal of Physics B: Atomic, Molecular and Optical Physics. 35:3887-3900

The 4f and 5p subvalence photoionization of atomic Tm has been investigated by combining high-resolution photoelectron spectroscopy and dichroism measurements of the laser-polarized atoms. The experimental results are compared to Hartree–Fock calcu
