{title2=$\Phi_0/\Phi_Q=1+k_Q\tau_0[Q]$}

For purely dynamic quenching of a single emitting population, $\Phi_0/\Phi_Q=\tau_0/\tau_Q=1+k_Q\tau_0[Q]$. The slope measures $k_Q\tau_0$, so determining a bimolecular quenching constant requires the unquenched lifetime or equivalent independent rate information.
