Abstract
Numerous studies to date are aimed at a better understanding of the optical dynamics of dissolved dye molecules. Most dyes exhibit prominent vibronic features in their absorption spectra. For impulsive excitation the initially excited state is a vibronic wave packet, that strongly influences the observed dynamics. Shank and co-workers were the first to recognize the importance of vibrational mode suppression towards optical dephasing measurements.[1,2] However, mode suppression based on time-integrated stimulated photon echo works only in systems that exhibit Bloch-like dynamics.
