| A two-dimensional finite cluster model is proposed to describe the coupling of low energy charge transfer and Frenkel states of an anthracene-like molecular crystal. The results confirm most of the qualitative conclusions of the extensively used linear crystal model, but suggest the necessity to review some of its quantitative results. Potential usefulness of the cluster model for the description of doped crystals is pointed out. |
