Abstract

The influence of exciton coupling on the optical properties of oligothiophenes is studied by means of optical and circular dichroism (CD) spectroscopy. The CD spectrum of a model compound, formed by two terthienyl chromophores arranged in a chiral orientation, displays two bands with opposite signs that can be related to the two Davydov components of the first optical transition. From correlated quantum-chemical calculations, the Davydov splitting is estimated to be on the order of 0.15-0.2 eV.
