Titel: "Microwaves, Transient Chirality, and Low Energy Collisions - An exploration of microwave spectroscopy and molecular beam control”

Microwave spectra can provide unique insights into tunnelling dynamics along internal degrees of freedom. Such motions can be associated with proton transfers, internal rotations (for example by methyl groups), or inversion motions such as in the ammonia molecule. Under certain circumstances tunnelling can connect two enantiomers of different handedness. We will explore how these tunnelling motions cause characteristic patterns in microwave spectra. A special focus of this talk will be on the system of deuterated ammonia ND3, which is currently considered as candidate for merged molecular beam collision studies of oriented dipoles. The presented investigations aim to further our understanding of tunnelling processes and intermolecular collisions. At the end of the talk a few ideas will be discussed, on how the presented concepts could be transferred to extend the experiments at Kassel University.
