Computer aided calculations, based on experimentally derived pairwise interaction constants, give the entire Brillouin zone exciton band profile. The Frenkel exciton model, with steeply falling-off interactions, is $used.1$ Results will be discussed, with special emphasis on the out-of-plane infrared active $(a2n)$ normal mode of Benzene, where the experimental data and the justification for the model have been quoted $previously.2$
