担当教員の一言
Intermolecular forces are important for collisional dynamics, energy transfer, line broadening, clustering, condensation, etc. High resolution spectroscopy of bound-bound transitions in weakly-bound molecules (“van der Waals complexes”) is now the most direct and precise technique to probe the intermolecular potential energy surface in the region of the attractive minimum. The lectures outline some history of this field, and focus on infrared and microwave studies of systems containing fundamental atoms and molecules like He, Ar, H2, N2, and CO.
