Notes:
The temporal evolution of the transient absorption response of light-harvesting antennae and dye molecules was studied. Using 40 - 90 fs pulses coherent nuclear motions were observed in intact membrane-bound photosynthetic light-harvesting pigment-protein complexes, bacteriochlorophyll α monomer and dye molecules in solutions. Computer simulations based on the harmonic Franck - Condon approximation and the Langevin equation describe qualitatively well the wavelength dependence of the oscillations of the mode when exciting and probing in the blue side of the spectrum.
