A solvent cage effect provides an upper bound for this parameter; reactions that saturate that bound are "diffusion-limited."
The ratio of fluorescence quantum yields in the presence and absence of a quenching agent are related to this parameter for the quenching process in the Stern–Volmer equation. A solvent cage effect provides an upper bound for this parameter; reactions that saturate that bound are "diffusion-limited." In mechanistic analysis, one computes the ratio of this parameter for a proton-transfer step to this parameter for the same reaction if the proton were replaced by a deuteron. If this constant has units of molar to the negative n, seconds to the negative one, then the corresponding elementary step has order n-plus-one. For 10 points, name this constant in reaction kinetics that is related to activation energy by the Arrhenius equation.
