An operational pH in aqueous dimethylsulfoxide based upon the acidity dependence of the rate of a simple ionic recombination reaction in the lowest excited singlet state

7-Hydroxy-1-naphthalenesulfonate (2-naphthol-8-sulfonate) monoanion demonstrates proton transfer in the lowest excited singlet state in DMSO–water mixtures as well as in pure water. The dissociation reaction of the directly excited monoanion is strongly solvent-dependent, and independent of solution...
