Radicals are abundant in a range of important gas-phase environments. They are prevalent
in the atmosphere, in interstellar space, and in combustion processes. As such …

The relationship between the shape of a molecule and its chemical reactivity is a central
tenet in chemistry. However, the influence of the molecular geometry on reactivity can be …

The energy dependence of the rates of the reactions between He+ and ammonia (NY3,
Y={H, D}), forming NY2+, Y and He as well as NY+, Y2 and He, and the corresponding …

The structure and quantum state of the reactants have a profound impact on the kinetics and
dynamics of chemical reactions. Over the past years, significant advances have been …

In molecular dynamics, a fundamental question is how the outcome of a collision depends
on the relative orientation of the collision partners before their interaction begins (the …

The control of movement and orientation of gas-phase molecules has become the focus of
many research areas in molecular physics. Here, ND 3 molecules are polarized in a …

The relationship between the shape of a molecule and its chemical reactivity is a central
tenet in chemistry. However, the influence of the molecular geometry on reactivity can be …

This thesis presents the experimental studies of quantum-controlled cold scattering of H 2
isotopologues (HD, D 2) with simple rare gas atoms (He, Ne) and diatom molecules D 2. In …

Chemical reactions are profoundly impacted by the properties of the interacting molecules,
including their structure and quantum state. Crossed-beam setups have been proven to be a …

Human interest in the artificial cooling of physical systems has a long and rich history.
Already in ancient times the Greeks and Romans used snow as a refrigerant for their drinks …
