  • The top part of the figure illustrates the system where pyrrole embedded inside an optical cavity. The bottom part represents the ground and excited state potential energy surfaces of pyrrole along NH dissociation. Optical nano cavities: a control knob for tuning photo-chemical reactions on a quantum level 2021-02-12 Researchers at Fysikum have theoretically investigated the light activated hydrogen abstraction reaction of pyrrole in an optical nano cavity. The electronic excitation of pyrrole with UV light triggers the hydrogen detachment reaction along the NH bond. Their latest paper investigates how strong light-matter coupling of a tightly confined electromagnetic mode can be used to steer this reaction. The results suggest that the cavity can hugely influence the reaction efficiency and open up alternative reaction pathways.
