To be able to model the absorption spectra of LH systems from an atomistic point of view, the key quantities are the site energies, excitonic couplings, spectral densities and transition dipole moments. Redfield-like approaches have been employed to determine the linear absorption of LH complexes. Recently, Cao and co-workers have developed the full second-order cummulant expansion (FCE) to calculate the linear absorption, an approach that neither includes the Markovian nor the secular approximation . The FCE method has been found to overcome several shortcomings of Redfield-like methods . Here, we have employed a code provided by Cupellini and Lipparini to determine the absorption spectra based on the FCE method . No information on the static disorder can be extracted from relatively short time trajectories, and thus no static disorder is included in the calculations of the absorption spectra.
