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

Popis výsledku v původním jazyce

Time dependence of the anisotropy of fluorescence in recently discovered cyclic antenna units of the BChl photosystem is modeled. Interaction with a bath and a static disorder here modeled as uncorrelated Gaussian disorder in the transfer integrals is taken into account. Parallel computer enviroment is used because one is forced to recalculate every physical quantity for several thousands of different realizations of disorder. Results for the ring LH4 with radial optical transition dipole arrangement are compared with those for the ring LH2 with the tangential one. The difference between LH2 and LH4 results for the static disorder in transfer integrals has an opposite sign in comparison with that one for the static disorder in local energies. Equivalent differences are shifted to a smaller times for the stronger interaction with a bath. ISSN 0302-9743 - Lecture notes in computer science
