Recent experiments demonstrated that chemical reaction rate constants can be suppressed or enhanced by resonantly coupling molecular vibrations to quantized radiation modes inside a Fabry-Pérot (FP) microcavity . This effect, known as vibrational strong coupling (VSC) modified chemical reactivity, has the potential to selectively slow down competing reactions or speed up a target reaction, thus achieving mode selectivity and offering a paradigm shift in chemistry. For example, VSC has been shown to selectively slow down one reaction over a competing reaction and revert the selectivities , enabling a new cavity-enabled bond-selective chemical transformation strategies in synthetic chemistry.
