The model for the B808-866 antenna of the green photosynthetic bacterium Chloroflexus aurantiacus based on femtosecond pump-probe studies is proposed. The three-dimensional structure of the B808-866 antenna is assumed to be similar to the structure of the B800-850 antenna of purple bacteria, i.e. it has the form of two concentric rings of N strongly coupled BChl866 pigments and of N/2 weakly coupled BChl808 monomers. The Qy transition dipoles of BChl808 and BChl866 molecules form the angles 43… CONTINUE READING
