Intersystem crossing (ISC), formally forbidden within nonrelativistic quantum theory, is the
mechanism by which a molecule changes its spin state. It plays an important role in the …

The past two decades have seen rapid developments in short-pulse X-ray sources, which
have enabled the study of nuclear and electronic dynamics by ultrafast X-ray spectroscopies …

The stability of Pt‐based catalysts for oxygen reduction reaction (ORR) in hydrogen fuel cells
is seriously handicapped by the corrosion of their carbon supports at high potentials and …

Starting from the late seventies, the progressively increased availability of synchrotron light
sources allowed the execution of experiments requiring a high X-ray flux in a continuous …

From a glass of water to glaciers in Antarctica, water–air and ice–air interfaces are abundant
on Earth. Molecular-level structure and dynamics at these interfaces are key for …

We review the tremendous advances in ultrafast X-ray science, over the past 15 years,
making the best use of new ultrashort X-ray sources including table-top or large-scale …

Platinum (II) complexes featuring conjugated aromatic ligands are widely studied in the
context of luminescence. Many such compounds have been discovered that display intense …

Photoexcited molecular trajectories on potential energy surfaces (PESs) prior to
thermalization are intimately connected to the photochemical reaction outcome. The excited …

We report the first photoinduced single-crystal-to-single-crystal (SCSC) phase transition of a
gold complex that involves the shortening of intermolecular aurophilic bonds. This is also the …

Light-driven chemical transformations provide a compelling approach to understanding
chemical reactivity with the potential to use this understanding to advance solar energy and …
