Abstrakt
Properties of light–harvesting (LH) pigment–protein complexes are strongly influenced by their interactions with environment. These interactions could be modeled by static and dynamic disorder. Influence of static disorder on B850 ring from LH2 complex of purple bacteria is investigated in present paper. The nearest neighbour approximation model of the ring is considered. Four types of uncorrelated Gaussian static disorder (fluctuations of transfer integrals, fluctuations of radial positions of molecules on the ring, fluctuations of angular positions of molecules on the ring and fluctuations of directions of molecular dipole moments) are taking into account. The most important statistical properties of the nearest neighbour transfer integral distributions for different strengths of static disorder are calculated. Results obtained for four above mentioned types of static disorder are discussed and compared.
