N2 - A first experimental verification of a theoretical prediction of a kinetic transition in a reversible binding reaction, AB ⇌ A + B, driven by the difference in effective lifetimes of the bound and the unbound states was presented. The kinetics of excited-state proton tranfer to solvent from a photoacid whose conjugate anionic base possesses an extremely short unbound anion lifetime were considered. Its solvent variation relative to the overall dissociation rate coefficient induces a transition in the kinetics, from power law to exponential.
