✦ Synopsis

Using a 6 fs optical pulse we have impulsively excited the entire manifold of Franck-Condon-connected vibronic levels for the So to S, transition in an organic dye in solution. Periodic perturbations to the absorption spectrum are observed as a consequence of the nuclear motion brought about by the coherent excitation of the manifold of vibrational levels.
