We employ multi-level Redfield theory and the equation-of-motion phase-matching approach to model two-dimensional electronic photon-echo signals of a vibronic dimer weakly coupled to an uncorrelated harmonic bath. The vibronic manifold of the dimer is formed by Franck-Condon active vibrational modes (one mode per monomer). We study the effect of the coupled exciton-vibrational dynamics on the two-dimensional photon-echo profiles. Our main focus is the relationship of the system coherences to the oscillatory behavior of the cross-peak intensities with population time. The work represents the first step towards detailed understanding of oscillative signatures in two-dimensional electronic photon-echo signals of vibronic oligomers. |
