Abstract

We explore the aqueous bimolecular neutralization reaction between a photoacid ROH and carboxylate bases OOCR’ and show that proton transfer in loose complexes (ROH··H2O··−OOCR’) occurs through intermediate water molecules in a sequential von Grotthuss type fashion, with the second step having similar reaction rates as those of the encounter complexes formed after mutual diffusion.
