Relative amplitudes of five exponential functions with corresponding time constants are extracted from a multiexponential global fitting of kinetics measured at various probing wavelengths for the PCP complex after 535-nm excitation. Negative amplitudes correspond to the rise, and positive to the decay, of the signal. For the 670- and 930-nm kinetics, negative amplitudes correspond to percentage from the total negative amplitude, and, for the 800- and 1,200-nm kinetics, correspond to the percentage from the total positive amplitude. In all cases, uncertainties of the lifetimes and amplitudes are within a limit of ±10%.
