Calculated absorption and CD-spectra for an elementary unit of Cf. aurantiacus chlorosomes (three hexagonally packed rod aggregates) with stack length of 20 (A) and 50 (B) molecules. The stick-spectra are convoluted with a normalized Gaussian profile of FWHM = 350 cm−1. Amplitude factor for the stick-components is 10−3. (C) Frozen-excitons in an elementary unit corresponding to A.
