For the physical and chemical description of molecules we can use three major models, which describe in very different ways what we understand as the internal structure of a molecule. My major research interests are aimed at the question how can we connect these three different views we have on molecules. To connect physics to quantum chemistry or to directly connect physics with chemistry is necessary to study molecules on an eigenstate level. We have to calculate and interpret the highly excited molecular rovibrational eigenstates and to set up spectroscopic experiments that allow to sample the potential energy surface at such high excitations. My research projects listed below are related to these basic questions of chemistry and physics. As spectroscopy is an important analytical tool, there is an impact of the presented experimental and theoretical results on the analytics of hot chemical objects in astrophysics such as stars and hot extrasolar planets, the analytics of combustion processes etc.
