Abstract EN
The Stern-Volmer constant is specified for the luminescence quenched by reversible ionization of excited molecules.
The exergonic branch of the Rehm-Weller free energy dependence of this constant is known to be a plateau determined by irreversible ionization being under diffusion control.
In the endergonic region the ionization is reversible and competes with the irreversible in-cage recombination of ions and their escape from the cage.
At strong Coulomb attraction the latter phenomenon is shown to be negligible compared to the former that determines the shape and location of the descending branch of the Rehm-Weller curve.
At weaker Coulomb attraction (at higher solvent polarity), this curve turns down at larger endergonicity.
The experimental data obtained in solvents of different polarities are put in order and in full accordance with present theory.
