Fig. 2.

Time dependent fluorescence emission from a single PSI complex from Synechocystis sp. PCC 6803. (A) Time series of spectra; the spectrum on top represents the time average. (B) Integrated intensity of the wavelength ranges Λ₁ (700.5–710 nm) and Λ₂ (712–725.5 nm). The blue line shows the time dependence of the intensity of the ZPL (Λ₁) and the green line represents the time dependence of a part of the broad emission (Λ₂). (C) Contour plot of the 2D-SCS for the sequence given in A. The color code is indicated on the right; positive values correspond to positive correlation, and negative values correspond to anticorrelation.
