Abstract

Buffer-mediated proton exchange reactions of a xanthenic dye were studied in the ground and the excited state by single molecule and bulk fluorescence techniques, respectively. The rate constant obtained supported the uniformity of the process in the ground and the excited state, and the need of adequate character of the buffer species to be able to promote excited-state reactions.
