Lineshapes of absorption- and circular dichroism spectra of molecular aggregates — •Klaus Renziehausen and Volker Engel — Institut für Physikalische und Theoretische Chemie, Universität Würzburg, Am Hubland, 97074 Würzburg

We perform time-dependent quantum calculations on the absorption and circular dichroism (CD) spectroscopy of molecular aggregates. The interplay between vibrational motion, geometry, electronic coupling and aggregate size to arrive at a certain lineshape is analyzed in detail. The numerical results are interpreted in terms of analytical considerations [1], and a comparison to experiment is given [2].
