Intermolecular Coupling Fluctuation Effect on Absorption and Emission Spectra for LH4 Ring - Full Hamiltonian Model

Popis výsledku v původním jazyce

Absorption and steady state fluorescence spectra of exciton states for ring molecular systems are presented. The peripheral cyclic antenna unit LH4 of the bacterial photosystem from purple bacteria can be modeled by such system. The cumulant-expansion method of Mukamel et al. is used for the calculation of spectral responses of the system with exciton-phonon coupling. Dynamic disorder, interaction with a bath, in Markovian approximation simultaneously with uncorrelated static disorder in transfer integrals are taking into account in our simulations. We compare calculated absorption and steady state fluorescence spectra for LH4 ring obtained within the full Hamiltonian model with our previous results within nearest neighbour approximation model for uncorrelated static disorder in transfer integrals. All calculations were done in software package Mathematica.
