Merger of the Laser Spectroscopy Experiments
2023/03/01
In early 2023, the VUV spectroscopy and UV-Vis spectroscopy experiments were combined. The existing molecular beam apparatus and the associated laser systems were dismantled and combined into one apparatus. At the new apparatus it is thus possible to generate clusters in a molecular beam and subsequently ionize them using the VUV laser system or perform photodissociation experiments using the UV-Vis laser system. Thus, both the ionization potentials and the optical properties of the clusters can be studied in a combined experiment.

Surprisingly Large Electronic g-Factors in p-Doped Lead Clusters

A Magnetic Molecular Beam Deflection Study Coupled with Modern Quantum Chemistry
Molecular Magnetism is a thriving field of research with remarkable discoveries being made with single-molecule magnets where d- and f-block elements serve as paramagnetic centers. Tetrel clusters p-doped with elements of the triel group also state magnetically highly relevant systems. If lead is chosen as tetrel cage element, the endohedral clusters are found to exhibit peculiar spin-orbit coupling effects with strongly impacted electronic g-factors.
