Vibronic spectra of homo- and hetero-dimer aggregates — •Johannes Wehner, Martin Kess, and Volker Engel — Universität Würzburg, Institut für Physikalische und Theoretische Chemie, Emil-Fischer-Str. 42, Campus Nord, 97074 Würzburg, Germany

We calculate two-dimensional photon-echo spectra of molecular dimers employing different wave-function based approaches. Calculations using perturbative, non-perturbative and phase-cycling methods are compared. The differences in spectra obtained for homodimers and heterodimers are investigated. The two-dimensional spectra are disscussed by comparing purely electronic level systems with their vibronic counterparts. In particular, the effect of orientational averaging is addressed.
