In recent years vibrational strong coupling (VSC) has emerged as a novel approach for performing mode specific chemistry. Pioneering experiments by Ebbesen and coworkers have demonstrated that coupling of the quantum light in an optical cavity to molecular vibrations can significantly suppress or enhance reaction rates. As further progress is being made in the experimental aspects , a clear theoretical explanation for the experimental results, particularly in the collective regime, remains elusive. However, several crucial insights have emerged, as evident from the recent reviews on our theoretical understanding to date. For example, it is now believed that coupling to the cavity mode results in altered intramolecular energy redistribution (IVR) pathways . It is also clear that the usual cavity quantum electrodynamics paradigm of two level systems and Rabi oscillations needs to be generalized in order to account for multilevel anharmonic molecular systems . Suggestions have been made for a careful assessment of the validity of the usual rate theories and thermodynamical interpretations upon coupling to the optical cavity. Moreover, there is now an active debate on the role of the dark states , disorder , and whether the proposed single molecule VSC mechanisms can survive the collective coupling limit . It is perhaps fair to say that given the myriad of questions that still remain unanswered, VSC and polariton chemistry continue to provide a fertile ground for gaining a deeper understanding of the * srihari@iitk.ac.in interaction between confined quantum light and complex molecular systems.
