摘要
This article provides a review of the authors' collaborative work on acid-base reactions under conditions allowing direct observation of mechanistic details of the proton transfer within reactive complexes of OH groups and the bases RCOO- (R=organic residues) in diffusion-assisted neutralization reactions by using time-resolved UV/Vis emission and IR absorption spectroscopy. We discuss the considerable insight gained by these experiments and outline the current status of the field.
