Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of WSEAS Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

ABSTRACT: Light–harvesting (LH) pigment–protein complexes interact with their environment, which strongly influences their properties. Slow fluctuations of environment could be modeled by different types of static disorder. LH2 complex from purple bacteria is investigated in present paper. This complex consists of two bacteriochlorophyll rings (B850 ring and B800 ring). Distributions of the nearest neighbour transfer integrals in B800 ring and the nearest neighbour transfer integrals connecting B850 and B800 ring are presented. The most important statistical properties are calculated, discussed and compared in case of uncorrelated static disorder in radial positions of bacteriochorophyll molecules.

KEYWORDS: B800 ring, B850 ring, LH2 complex, Hamiltonian, static disorder, transfer integral distributions
