Exciton-phonon coupling in conjugated organic molecules

Georg Heimel, Alexander Pogantsch, Egbert Zojer

Research output: Contribution to journalArticlepeer-review


Chosing the oligo(para-phenylenes) as model systems, several aspects of excited state geometry relaxation are studied with correlated quantum-chemical methods. In particular, the dependence of the exciton binding energy on the oligomer length will be discussed and compared to the respective Stokes shifts. Furthermore, the effect of exciton self localization on the Davydov splitting and the optical activity of the Davydov components in molecular crystals will be discussed.
