LH1 and LH2 kinetic traces for the different exciton bands. Depicted are the center frequencies of the exciton states in LH1 and LH2. The time traces show the behavior of the two main exciton bands after the dump arrived. Slight oscillatory features, which result from a vibrational wavepacket instigated by the dump pulse, overlay the traces during the first 500 fs after dumping. The LH1 traces are translated from 1 ps to 6 ps to depict their kinetics relative to LH2.
