Simulation of molecular ring emission spectra: localization of exciton states and dynamics

Original language description

Computer simulation of steady state fluorescence spectra of the ring molecular system is presented in this paper. The cyclic antenna unit LH2 of the bacterial photosystem from purple bacterium Rhodopseudomonas acidophila can be modeled by such system. Three different models of uncorrelated static disorder are taking into account in our simulations: Gaussian disorder in local excitation energies, Gaussian disorder in nearest neighbour transfer integrals and Gaussian disorder in radial positions of molecules in the ring. Dynamic disorder, interaction with a bath, is also included in Markovian approximation. The cumulant-expansion method of Mukamel et al. is used for the calculation of spectral responses of the system with exciton-phonon coupling. The peak position of single ring spectra and localization of exciton states depend on realization of static disorder and is also influenced by dynamic disorder. We discuss different types of exciton dynamics too, that are coupled to above mentio
