Abstract Interaction between light and matter results in new quantum states whose energetics can modify chemical kinetics. In the regime of ensemble vibrational strong coupling (VSC), a macroscopic number $$N$$ N of molecular transitions couple to each resonant cavity mode, yielding two hybrid light–matter (polariton) modes and a reservoir of $$N-1$$ N − 1 dark states whose chemical dynamics are essentially those of the bare molecules. This fact is seemingly in opposition to the recently reported modification of thermally activated ground electronic state reactions under VSC. Here we provide a VSC Marcus–Levich–Jortner electron transfer model that potentially addresses this paradox: although entropy favors the transit through dark-state channels, the chemical kinetics can be dictated by a few polaritonic channels with smaller activation energies. The effects of catalytic VSC are maximal at light–matter resonance, in agreement with experimental observations.

Award of Medals 1962 The Copley Medal is awarded to Sir Cyril Hinshelwood, O.M., F. R .S. The contributions of Sir Cyril Hinshelwood to chemical research have been recognized repeatedly, and universally. Most of his scientific work has been concerned with the mechanism of a wide variety of chemical reactions, homogeneous and heterogeneous, and in all states of aggregation. These have included processes of fundamental importance in both chemistry and biology. His work has been characterized by a flair for the elucidation of complex processes by the ingenious planning of relatively simple experiments, together with a remarkable insight into the implication of the results. He has influenced the whole pattern of research in chemical kinetics during the past 40 years.
