Journal ArticleDOI
Charge separation in the reaction center of photosystem II studied as a function of temperature
Marie Louise Groot,Frank van Mourik,Camiel Eijckelhoff,Ivo H. M. van Stokkum,Jan P. Dekker,Rienk van Grondelle +5 more
TL;DR: It is suggested that the slow energy transfer from the trap state to P680 plays an important role in the kinetics of radical pair formation at room temperature.
Journal ArticleDOI
Fluorescence and absorption spectroscopy of the weakly fluorescent chlorophyll a in cytochrome b6f of Synechocystis PCC6803
Erwin J.G. Peterman,Stephan Olav Wenk,Tõnu Pullerits,Lars-Olof Pålsson,Rienk van Grondelle,Jan P. Dekker,Matthias Rögner,Herbert van Amerongen +7 more
TL;DR: A spectroscopic characterization of the chlorophyll a (Chl) molecule in the monomeric cytochrome b6f complex (Cytb6f) isolated from the cyanobacterium Synechocystis PCC6803 shows that the Chl binds to a well-defined pocket of the protein and experiences several close contacts with nearby amino acids, and it is concluded that the electron-phonon coupling is moderately strong.
Journal ArticleDOI
Three pulse echo peak shift measurements on the B820 subunit of LH1 of Rhodospirillum rubrum
TL;DR: Three pulse photon echo peak shift measurements 3PEPS of the detergent isolated B820 subunit of the light harvesting complex of Rhodospirillum rubrum are presented and compared with3PEPS data for the LH1complex of Rhodobacter sphaeroides, suggesting that excitation is delocalized over only a dimer unit.
Journal ArticleDOI
Singlet-singlet annihilation at low temperatures in the antenna of purple bacteria
Marcel Vos,Rienk van Grondelle,Fred W. van der Kooij,Dan van de Poll,Jan Amesz,Louis N.M. Duysens +5 more
TL;DR: In this article, it was shown that the number of connected antenna molecules between which energy transfer is possible decreases from about 1000 to about 150 when the temperature is lowered from 298 to 4 K.
Journal ArticleDOI
Electric field effects on the chlorophylls, pheophytins, and beta-carotenes in the reaction center of photosystem II
Raoul N. Frese,Marta Germano,Frank L. de Weerd,Ivo H. M. van Stokkum,Anatoli Ya. Shkuropatov,Vladimir A. Shuvalov,Hans J. van Gorkom,Rienk van Grondelle,Jan P. Dekker +8 more
TL;DR: The results favor a model that locates both beta-carotene molecules at the same side of the complex, and the red-shifted Stark spectra can be explained by a mixing of exciton states with a charge-transfer state of about equal energy.
