Site-specific Interrogation of an Ionic Chiral Fragment During Photolysis Using an X-ray Free-Electron Laser

Markus Ilchen, Philipp Schmidt, Nikolay M. Novikovskiy +24

Short-wavelength free-electron lasers with their ultrashort pulses at high intensities have originated new approaches for tracking molecular dynamics from the vista of specific sit…

Applying Bayesian Inference and deterministic anisotropy to retrieve the molecular structure distribution from gas-phase diffraction experiments

Kareem Hegazy, Varun Makhija, Phil Bucksbaum +12

Currently, our general approach to retrieving molecular structures from ultrafast gas-phase diffraction heavily relies on complex ab initio electronic or vibrational excited state…

A self-referenced in-situ arrival time monitor for X-ray free-electron lasers

Michael Diez, Andreas Galler, Sebastian Schulz +11

We present a novel, highly versatile, and self-referenced arrival time monitor for measuring the femtosecond time delay between a hard X-ray pulse from a free-electron laser and an…

Diffractive Imaging of Coherent Nuclear Motion in Isolated Molecules

Jie Yang, Markus Guehr, Xiaozhe Shen +17

Observing the motion of the nuclear wavepackets during a molecular reaction, in both space and time, is crucial for understanding and controlling the outcome of photoinduced chemic…

Diffractive imaging of a molecular rotational wavepacket with femtosecond Megaelectronvolt electron pulses

Jie Yang, Markus Guehr, Theodore Vecchione +20

Imaging changes in molecular geometries on their natural femtosecond timescale with sub-Angstrom spatial precision is one of the critical challenges in the chemical sciences, since…
