Model refinement: The excited-state chemistry of protochlorophyllide a, the precursor of chlorophyll a by means of picosecond time-resolved fluorescence (see figure) is discussed. A detailed spectral characterization of the emission significantly refines the kinetic model deduced from ultrafast absorption measurements in terms of a branching of the initial excited-state population into a reactive and a nonreactive path.
