Fig. shows the fitted forward rate constants from the propagated acceptor populations with a fixed δ c = 350 meV and Q ranging over Q ∈ [10, ∞]. The rate constant's lack of dependence on λ D that was seen in Fig. for Q = 100 is also seen in Fig. across all values of Q. This further supports the idea that the dark states do not significantly impact the overall PMET process from the UP to the acceptor states with large positive detunings. The dependence of the rate constant across Q is similar to that seen in Fig. . Additionally, the rate constants in Fig. (with collective coupling √ Ng c = 150 meV) are almost as large as those rate constants at resonance with √ Ng c = 300 meV in Fig. . Notably, the rate constant for λ D = 50 meV and Q = 10 is 10 3 times larger than outside the cavity, exemplifying how the cavity can still significantly enhance PMET reactivity even with significant molecular disorder and cavity loss by CW driving to a positively detuned UP state.
