TL;DR: A competing charge transfer pathway at the enzyme-electrode interface that short-circuits the known water-oxidation pathway is identified: photo-induced O2 reduction occurring at the chlorophyll pigments.

TL;DR: A functional model is presented that takes into account the presence of several fluorescent species whose concentrations can be resolved provided their fluorescence quantum yields are known and a positive correlation was found between the amount of PBfree and the rate constants describing the binding of the activated orange carotenoid protein to PB, responsible for non-photochemical quenching.

TL;DR: Evidence is presented that in these mutants the LH1 and LH2 complexes are spectrally inhomogeneous and each contain an additional, long-wavelength-absorbing BChl, which may be mediated by the presence of reaction centres.

TL;DR: In this paper, a brief description of light harvesting in photosynthesis is given, followed by an introduction to two-dimensional electronic spectroscopy, in which this spectroscopic technique can be used to indicate coherent contributions to energy transfer dynamics.

TL;DR: It is demonstrated that, although excitations in the B800 ring are localized due to disorder, thermal effects, and phonons, there are still sizable excitonic effects producing shift, narrowing, and asymmetry of the spectra.
