✦ Synopsis

3aminoacridme

(I) has been used to extend the quantitation of acited-state proton-transfer kinetics in concentrated acid media to ==13 hl sulfuric acid. The hydration requirement of tire reaction and the reasons for its not attaining equilibrium witbin the lifetime of the excited state are discussed.

Fluorimetric titrations of 4-hydroxydiphenyl ether and its anion give stretched sigmoid curves with two inflection points. This reveals that the rates of excited state proton exchange are comparable to the rates of deactivation of the conjugate pair. These curves are analyzed using the lifetimes of
