With the current theory, we recommend future experimental investigations to focus on (1) confirming the scaling relation of k/k 0 with respect to ω R (or N ) with more data points. (2) confirming potentially null VSC results in the alcoholysis reaction between 2,4-toluenediisocyanate and chloraldhydrate due to its low barrier , which will greatly inform the VSC mechanism, given that the similar alcoholysis reaction between phenylisocyanate and cyclohexanol has shown VSC resonance suppression effects . (3) More data points on the cavity frequency dependence of k/k 0 to provide the shape of the action spectrum , and (4) control the dipole orientations (so one can control χ in Eq. 11) and measure the corresponding VSC effects.
