The anisotropy of fluorescence in ring units III: Tangential versus radial dipole arrangement

Computer Simulation of the Anisotropy of Fluorescence in Ring Molecular Systems: Tangential vs. Radial Dipole Arrangement

“…4) has an opposite sign in comparison with the result for the static disorder in local energies as shown in Fig. 2 in [19].…”

“…Let us look at time decay of the anisotropy of fluorescence in the molecular ring with radial arrangement r r (t) -LH4, octameric one. Recently we discussed [19] results in the case of one type of the static disorder -uncorrelated Gaussian disorder in the local energies.…”

“…Recently we have investigated the time dependence of the anisotropy of fluorescence for newly discovered type of the molecular ring, the LH4 ring with the uncorrelated static disorder in local energies [19]. Main goal of our present investigation is the comparison of the time dependence of the anisotropy of fluorescence after an impulsive excitation for two molecular rings: for molecular ring with tangentially arranged optical transition dipoles r t (t), like in LH2, as well as for the radially arranged one r r (t) like in LH4 [1].…”

Lost of coherence due to disorder in molecular rings

“…Our main goal is a comparison of results for three models of uncorrelated Gaussian static disorder in molecular ring: in local energies, in transfer integrals and in radial positions of molecules. We are extending in such a way our previous investigation of the rings with different symmetries and arrangement of optical dipole moments [11][12][13].…”
