Using = 40 fs pulses we have observed coherent nuclear motions in intact membrane bound photosynthetic light-harvesting pigment-protein complexes. Computer simulations based on the harmonic Franck-Condon approximation and the Langevin equation describe qualitatively well the temperature and pulse wa

Electron spin echoes of triplet states in zero field were optically detected using the singlet ground-state absorbance. The technique has been applied to reaction centers of the photosynthetic bacterium Rhodobacter sphaeroides R-26. The spin-spin relazation time T, of the triplet state of the primar
