| Description
| - Bylo zkoumáno rozdělení energetické separace E(k=+-1) a relativní orientace dipólových momentů v prstenci B850 z purpurové bakterie Rhodopseudomonas acidophila. Byly porovnány čtyři typy nekorelovaného statického nepořádku: (A) Gaussovský nepořádek v lokálních excitačních energiích, (B) Gaussovský nepořádek v transfer integrálech, (C) Gaussovský nepořádek v radiálních posicích molekul, (D) Gaussovský nepořádek v úhlových posicích molekul. Je zahrnuta též možná eliptická deformace prstence. Naše výsledky jsou korelovány s dostupnými experimentálními daty [C. Hofmann et. al., Chem. Phys. Lett. 395 (2004) 373]. (cs)
- The time dependence of the anisotropy of fluorescence after an impulsive excitation in the molecular ring (resembling the B850 ring of the purple bacterium Rhodopseudomonas acidophila) is calculated. Fast fluctuations of the environment are simulated by dynamic disorder and slow fluctuations by uncorrelated static disorder. Without dynamic disorder modest degrees of static disorder are sufficient to cause the experimentally found initial drop of the anisotropy on a sub-100 fs time scale. In the present investigation we are comparing results for the time-dependent optical anisotropy of the molecular ring for four models of the uncorrelated static disorder: Gaussian disorder in the local energies (model A), Gaussian disorder in the transfer integrals (model B), Gaussian disorder in radial positions of molecules (model C) and Gaussian disorder in angular positions of molecules (model D). Both types of disorder-static and dynamic-are taken into account simultaneously.
