Title: Theory of aggregates of photosynthetic molecules: spectroscopy, structure, transport phenomena Author: Ján Lalinský Institute: Institute of Physics of Charles University Supervisor of the master thesis: RNDr. Tomáš Mančal, PhD., Institute of Physics of Charles University Abstract. A theory of absorption of light in an isotropic solution of molecules was formulated on the basis of electromagnetic theory of par- ticles with attention to relativistic nature of their interaction and its im- pact on the spectrum of circular dichroism. Calculations of the absorption spectra of simple systems were performed to demonstrate the properties of the mathematical model. Also calculations of the absorption spectra of the models of the bacteriochlorophyll dimer which were proposed as possible basic unit in the lamellar model of the interior of a chlorosome were performed. The experimental spectra of solution of non-aggregated bacteriochlorophyll were used to fit the parameters of the mathematical model of the molecule and for these parameters the spectra of the pro- posed models of a dimer were calculated. It has been found that the new non-electrostatic terms in the description of the mutual interaction of the parts of the molecule are negligible for calculations of ordinary absorption spectrum, but they have...
