Following structural dynamics in real time is a fundamental goal towards a better
understanding of chemical reactions. Recording snapshots of individual molecules with …

Over the last 20 years, XUV and X-ray free-electron lasers have enabled a wide variety of
time-resolved experiments that have dramatically advanced our understanding of ultrafast …

X-ray free-electron lasers enable the investigation of the structure and dynamics of diverse
systems, including atoms, molecules, nanocrystals and single bioparticles, under extreme …

First-principles calculations are employed to elucidate the modes of attosecond charge
migration (CM) in halogenated hydrocarbon chains. We use constrained density functional …

The dynamics following laser-induced molecular photodissociation of gas-phase CH 2 BrI at
271.6 nm were investigated by time-resolved Coulomb-explosion imaging using intense …

The photodissociation dynamics of CH 3 I and CH 2 ClI at 272 nm were investigated by time-
resolved Coulomb explosion imaging, with an intense non-resonant 815 nm probe pulse …

Ultrafast H2+ and H3+ formation from ethanol is studied using pump-probe spectroscopy
with an extreme ultraviolet (XUV) free-electron laser. The first pulse creates a dication …

Inner-shell photoelectron spectroscopy provides an element-specific probe of molecular
structure, as core-electron binding energies are sensitive to the chemical environment. Short …

In pump-probe experiments employing a free-electron laser (FEL) in combination with a
synchronized optical femtosecond laser, the arrival-time jitter between the FEL pulse and the …

We present the main specifications of the newly constructed Swiss Free Electron Laser,
SwissFEL, and explore its potential impact on ultrafast science. In light of recent …
