| Outline of Final Research Achievements |
The electronic and nuclear dynamics of photosynthetic membranes, pigment-protein complexes and isolated pigments from photosynthetic purple bacteria have been investigated by means of nonlinear spectroscopy. The former experimental setup for the coherent spectroscopic measurements has been rearranged into the double-pulse configuration to extract the information in the spectral domain. By changing the temporal separations of excitation pulses, artificial enhancement of coupled modes that are intrinsically forbidden in photosynthetic pigments and significant suppression of allowed fundamental modes have been attained in the four-wave mixing configuration. In the pump-probe configuration, an electronic decoherent process within 100 femtoseconds has been observed.
