Research on isolated attosecond pulses (IAPs) based on high-order harmonic generation
changed substantially around 2010. Before then, the Ti: sapphire laser was the de facto …

Since the first demonstration of the generation of attosecond pulses (1 as= 10− 18 s) in the
extreme-ultraviolet spectral region, several measurement techniques have been introduced …

Attosecond-pump/attosecond-probe experiments have long been sought as the most
straightforward method for observing electron dynamics in real time. Although there has …

We show that attosecond core-level spectroscopy is a powerful tool for investigating
molecular dynamics due to its combined attosecond temporal resolution and the broad …

Free-electron lasers and high-harmonic-generation table-top systems are new sources of
extreme-ultraviolet to hard X-ray photons, providing ultrashort pulses that are intense …

Super-reducing excited states have the potential to activate strong bonds, leading to
unprecedented photoreactivity. Excited states of radical anions, accessed via reduction of a …

Over the last few decades, conical intersections (CoIns) have grown from theoretical
curiosities into common mechanistic features of photochemical reactions, whose function is …

Understanding the relaxation pathways of photoexcited molecules is essential to gain
atomistic-level insight into photochemistry. We performed a time-resolved study of ultrafast …

Proton transfer is one of the most fundamental events in aqueous-phase chemistry and an
emblematic case of coupled ultrafast electronic and structural dynamics,. Disentangling …

The radical anion of 9, 10-dicyanoanthracene (DCA) has been suggested to be a promising
chromophore for photoredox chemistry, due to its nanosecond excited-state lifetime …
