Abstract
Absorption and CW and time-resolved fluorescence nleasurements were pe rformed to investigate the excited-state acid-base kinetics and equili bria of norharman in aqueous solutions of different pH. Four different excited-state species, namely cation, neutral molecule, anion,and zwi tterion, can be distinguished. Rate-equations were applied to explain the observed decay curves and to calculate the pH-dependent kinetic pa rameters for the transitions between the species.
