99. INVESTIGATING THE ELECTRONIC STRUCTURE OF MOLECULES IN SOLUTION WITH X RAY SPECTROSCOPY

This contribution will present applications of soft and tender X
ray absorption
spectroscopy (XAS) and resonant inelastic X ray scattering (RIXS) to small molecules in
solution to probe their electronic charge density by and of quantum chemical modeling. T his
information allows to correlate charge density and molecular structure in order to understand
their interplay and thereby inform...

4. TIME-RESOLVED RIXS AND SAXS AT THE SCS INSTRUMENT OF EUROPEAN XFEL

The Spectroscopy and Coherent Scattering (SCS) instrument of the European X-ray free-electron laser (EuXFEL) provides time-resolved tools to investigate electronic, spin and lattice structure of complex materials and reveal the material dynamics on the nanometer length scale and the femtosecond time scale using optical lasers as pump and soft X-rays as probe.
Femtosecond lasers are important...

86. TOWARDS NEW TIME AND FREQUENCY STANDARDS WITH 45SC AND EUXFEL

Nowadays, the most precise clocks are atomic clocks. These devices use the transition of cesium (133Cs) atoms between two electronic states to control the frequency and they can measure time with an accuracy of 1 second within 300 million years. To improve this precision, scientists want to use the resonant transition between the ground and excited levels of the nuclei of long-lived...

100. ULTRAFAST STRUCTURAL TRANSFORMATIONS IN FE STUDIED BY TIME-RESOLVED XRD

The atomic structure of the thin Fe layer after sub-ps pulsed laser annealing was investigated using time-resolved X-ray diffraction [1]. Due to the strong electron-phonon coupling, the laser pulse energy is transferred to the lattice at within approx. 1 ps. This rapid heating results in ultrafast melting. However, below the threshold of the complete melting, solid-solid structural...
