Exciton modeling of energy-transfer dynamics in the LHCII complex of higher plants: A Redfield theory approach
Article Abstract:
An exciton model is proposed for the peripheral plant light-harvesting complex LHCII that allows us to explain the absorption (OD) and linear dichroism (LD) spectra, the superdiance (SR), the pump-probe transient adsorption (TA), the three-pulse photon echo peak shift (3PEPS), and transient grating (TG) kinetics at different excitation wavelengths. The spectral density of the exciton-phonon coupling adjusted from the fit allowed to determine the time scales and pathways of energy transfer in LHCII.

Electronic and vibrational coherence in the core light-harvesting antenna of Rhodopseudomonas viridis
Article Abstract:
The wavelength-dependent oscillatory features in the pump-probe kinetics of the core LH1 antenna of Rhodopseudomonas (Rps) virdis are explained. The specific property of Rps.virdis is the cause for the strong oscillations in the pump-probe kinetics and for the pronounced heterogeneity of the absorption band due to combined effect of the exciton splitting and vibrational side-bands.

Exciton (De) localization in the LH2 antenna of Rhodobacter sphaeoides as revealed by relative difference absorption measurements of the LH2 antenna and the B820 subunit
Article Abstract:
A relative difference absorption (pump-probe) is used to measure the B820 subunit of Rhodospirillum rubrum and the LH2 antenna of the Rhodobacter sphaeroides. The measurements are compared.
