Coherent nuclear motions and exciton state dynamics in photosynthetic light-harvesting pigments

Summary, in English

Coherent nuclear oscillations in two intact photosynthetic light-harvesting pigments were observed for the first time using the approx. 40-fs tunable pulses from a mode-locked Ti:Sa laser. Furthermore, steady-state optical spectroscopy and theoretical calculations provide evidence that exciton states are present in the pigments. The possible antenna configurations that would give rise to the observed excited-state absorption and polarization were investigated.
