| Popis: | The temperature dependence of absorption and selectively excited fluorescence spectra of B820 subunit of the bacterial light-harvesting antenna is modelled by using the impurity center theory ofoptical spectra. In order toget acceptable agreement between theory and experiment, we suggest that due to the dimeric nature of B820, the electronic transition is weakly coupled to a rather broad distribution of protein phonons. |
