Time-resolved photoelectron spectroscopy (TRPES) has become one of the most
widespread techniques for probing nonadiabatic dynamics in the excited electronic states of …

Elementary events that determine photochemical outcomes and molecular functionalities
happen on the femtosecond and subfemtosecond timescales. Among the most ubiquitous …

Conical intersections (CoIns) play an important role in ultrafast relaxation channels. Their
monitoring remains a formidable experimental challenge. We theoretically compare the …

We consider the formation of vibrationally-induced transient electronic coherences driven by
conical intersection (CI)-mediated population transfer between two electronic states. By …

The role of quantum-mechanical coherences in the elementary photophysics of functional
optoelectronic molecular materials is currently under active study. Designing and controlling …

Ultrafast laser excitation can trigger complex coherent dynamics in molecules. Here, we
report attosecond transient-absorption experiments addressing simultaneous probing of …

The field of angle-resolved molecular photoelectron spectroscopy is reviewed, with
emphasis on foundations and most recent applications in different regimes of light–matter …
