Intense ultrashort light pulses comprising merely a few wave cycles became routinely
available by the turn of the millennium. The technologies underlying their production and …

The development of femtosecond time-resolved methods for the study of gas-phase
molecular dynamics is founded upon the seminal studies of Zewail and co-workers, as …

Crossings of electronic potential energy surfaces in nuclear configuration space, known as
conical intersections, determine the rates and outcomes of a large class of photochemical …

▪ Abstract Femtosecond time-resolved photoelectron spectroscopy is emerging as a useful
technique for investigating excited state dynamics in isolated polyatomic molecules. The …

Dynamic processes at the molecular level occur on ultrafast time scales and are often
associated with structural as well as electronic changes. These can in principle be studied …

▪ Abstract We review prototype studies in the area of quantum control with femtosecond
lasers. We restrict this discussion to atoms and diatomics under gas-phase collision-free …

▪ Abstract Time-resolved photoelectron spectroscopy (TRPES) has become a powerful new
tool in studying the dynamics of molecules and clusters. It has been applied to processes …

Photoelectron circular dichroism (PECD) is a CD effect up to the ten‐percent regime and
shows contributions from higher‐order Legendre polynomials when multiphoton ionization …

Interferences of free electron wave packets generated by a pair of identical, time-delayed,
femtosecond laser pulses which ionize excited atomic potassium have been observed. Two …

We investigate the applicability of time-resolved photoelectron spectroscopy to excited state
intramolecular proton transfer (ESIPT) and internal conversion dynamics in the model …
