Abstract. Due to dispersion forces, many aromatic molecules in concentrated solutions form complexes, particularly if they are electronically excited. In this physical chemistry experiment, the student is introduced to resonance energy transfer (RET) and the accompanying quenching that is observed for the donor molecule.
