If all molecules are perfectly aligned with the cavity field, the coupling strength per molecule η c is bound to be very weak (∼ Ω R,N / √ N ). Recent theoretical work suggests that disorders of the molecular dipole distribution along the field polarization will create local strong coupling spots , and in these "hot spots", only a few molecules are strongly coupled to the cavity (which resembles a form of spin glass). If this is the case in the VSC experiments, then combining the kVSC in Eq. 17 with the disorder-enhanced local coupling theory in Ref. would likely explain the VSC enabled effect. On the other hand, the VSC-induced rate constant changes could originate from a non-trivial collective effect even though the individual η c is tiny . In this case, one has the scenario that Ω
