Autor: J. Aschenbrücker, M. Buback, U. Steegmüller, Jörg Schroeder, Nikolaus P. Ernsting

Publikováno v: Berichte der Bunsengesellschaft für physikalische Chemie. 102:965-971

Picosecond UV pump/IR probe experiments were carried out on bis(1-naphthoyl)peroxide (1) and on tert-butyl-peroxy-2-naphthylcarbonate (2) dissolved in CCl4. After excitation by a 308 nm pulse the formation of CO2 is measured with a time resolution of

Autor: S, Neerken, Y Z, Ma, J, Aschenbrücker, K A, Schmidt, F R, Nowak, H P, Permentier, T J, Aartsma, T, Gillbro, J, Amesz

Publikováno v: Photosynthesis research. 65(3)

Properties of the excited states in reaction center core (RCC) complexes of the green sulfur bacterium Prosthecochloris aestuarii were studied by means of femtosecond time-resolved isotropic and anisotropic absorption difference spectroscopy at 275 K

Groundstate vibrational coherence in chlorosomes of the green sulfur photosynthetic bacterium Chlorobium phaeobacteroides

Autor: Ying-Zhong Ma, Mette Miller, J. Aschenbrücker, Tomas Gillbro

Publikováno v: Ma, Y-Z, Aschenbrucker, J, Miller, M & Gillbro, T 1999, ' Groundstate vibrational coherence in chlorosomes of the green sulfur photosynthetic bacterium Chlorobium phaeobacteroides ', Chemical Physics Letters, vol. 300, pp. 465-472 .

Femtosecond transient absorption measurements have been performed on the bacteriochlorophyll e -containing chlorosomes of Chlorobium phaeobacteroides . Oscillations superimposed on the initial part of the kinetics and damped within 2 ps were observed

Redox- and Pump Intensity Dependence of Energy Transfer in Chlorosomes of cb. Phaeobacteroides

Autor: J. Aschenbrücker, Ying-Zhong Ma, Mette Miller, Tomas Gillbro

Publikováno v: Photosynthesis: Mechanisms and Effects ISBN: 9780792355472

Chlorosomes are the main antenna complexes of green sulfur bacteria containing rodlike aggregates of bacteriochlorophyll c, d, e (Bchl), and a small amount of Bchl a located in the chlorosomal baseplate. The latter is believed to mediate the energy t

Relaxation and Trapping In Reaction Centers of the Green Sulfur Bacterium Prosthecochloris Aestuarii

Autor: Christof Francke, Sieglinde Neerken, Hjalmar P. Permentier, T. Gillbro, Jan Amesz, Kristiane A. Schmidt, J. Aschenbrücker, Ying-Zhong Ma, Thijs J. Aartsma

Publikováno v: Photosynthesis: Mechanisms and Effects ISBN: 9780792355472

The reaction center of green sulfur bacteria resembles that of Photosystem I of green plants. The primary donor, P840, is a bacteriochlorophyll (BChl) a dimer and the primary electron acceptor, A0, is a pigment absorbing near 670 nm, (Chl a 670). In

The Role Of Bacteriochlorophyll E And Carotenoids In Light Harvesting In Brown-Colored Green Sulfur Bacteria

Autor: Mette Miller, Ying-Zhong Ma, Raymond P. Cox, Tomas Gillbro, J. Aschenbrücker

Publikováno v: Photosynthesis: Mechanisms and Effects ISBN: 9780792355472

Green sulfur bacteria are commonly found in deep, sulfide-rich stratified lakes. In these habitats the intensity of the illumination is low and the wavelength distribution depends on the absorption in the overlying layer. Brown-colored green sulfur b
