Part of the Advances in Photosynthesis and Respiration book series (AIPH, volume 29)

We discuss how the light harvesting in photosystem I, photosystem II and in light-harvesting complex II can be modeled at a quantitative level by taking into account the exciton structure of the chromophores in the pigment-protein complexes, static (conformational) disorder, and coupling of electronic excitations and charge-transfer (CT) states to fast nuclear motion. We show examples of simultaneous fitting of linear and nonlinear (time-dependent) spectral responses based on the modified Redfield theory that resulted in a consistent physical picture of the energy and electron transfer reactions. This picture (including the time scales and pathways of energy and charge transfer) allows a visualization of the excitation dynamics, thus leading to a deeper understanding of how photosynthetic pigment-proteins perform their function in harvesting of solar energy.
