Electronic structure of diatomic molecules-spectroscopic investigation

Ultracold molecules provide an ideal platform for exploring fundamental aspects of quantum physics and chemistry. Diatomic molecules with permanent electric dipole moments have already been used to achieve the first ultracold controlled chemical reactions, perform precision measurements, and enable quantum simulations of many-body dynamics. Moreover, recent prospects for their application in quantum computing have driven the development of single-molecule control using optical tweezers. The rapid progress in this field has motivated an increasing number of research groups worldwide to investigate polar molecules at ultralow temperatures. A detailed understanding of molecular electronic structure is essential for the development of such experiments. This presentation will focus on the challenges of spectroscopic investigations of the electronic structure of selected diatomic molecules.
