Absorption spectra of the different AEC fractions. The absorption spectra were normalized to the QY band of Chl a. For the measurements the Chl concentration of the isolated pigment protein complexes was adjusted in such a way that the absorption in the blue part of the spectrum did not exceed absorption values of 1. Figure 2a shows the absorption spectrum in the wavelength range from 350 to 750 nm, Fig. 2b presents a detailed view of the red absorption maximum of Chl a. Figure 2 shows typical absorption spectra.
