Probing the geometry dependence of molecular dimers with 2D-vibronic spectroscopy — •Joachim Seibt, Klaus Renziehausen, Dimitri V. Voronine, and Volker Engel — Institut für Physikalische Chemie, Am Hubland, 97074 Würzburg

Two-dimensional vibronic correlation spectra of molecular dimers are calculated, taking a single vibration in each monomer into account. Within the employed wave function approach, the coupling to a surrounding is included only phenomenologically. It is shown that this offers a straightforward understanding of the spectra. The influence of the relative orientation of the monomer transition dipole-moments and the electronic coupling strength is investigated. Employing a model for perylene bisimide we predict the 2D-spectra for the monomer and dimer configurations.
