Photosynthetic Pigments in Diatoms
Photosynthetic pigments are bioactive compounds of great importance for the food, cosmetic, and pharmaceutical industries. They are not only responsible for capturing solar energy to carry out photosynthesis, but also play a role in photoprotective processes and display antioxidant activity, all of which contribute to effective biomass and oxygen production. Diatoms are organisms of a distinct ...

متن کاملTwo-exciton spectroscopy of photosynthetic antenna complexes: Collective oscillator analysis
The linear and third-order polarizabilities of the light-harvesting antennae of photosynthetic bacteria and green plants are calculated using an equation of motion approach which maps the system onto a coupled set of anharmonic excitonic oscillators. The oscillator representation is shown to have several advantages over the traditional picture based on properties of individual global eigenstate...
متن کاملThe Design of Natural Photosynthetic Antenna Systems
The nanoscale dimensions of the photosynthetic complexes are of critical importance for their effective function. Ultrafast spectroscopic studies by ourselves and by other groups, advances in obtaining high-resolution structural models, and more realistic light-harvesting models have revealed that the electronic interactions between the light-absorbing components in photosynthetic antenna compl...
متن کاملMicroscopic quantum coherence in a photosynthetic-light-harvesting antenna.
We briefly review the coherent quantum beats observed in recent two-dimensional electronic spectroscopy experiments in a photosynthetic-light-harvesting antenna. We emphasize that the decay of the quantum beats in these experiments is limited by ensemble averaging. The in vivo dynamics of energy transport depends upon the local fluctuations of a single photosynthetic complex during the energy t...
