**The salient features in the absorption and emission spectra of Ξ±T4 aggregates** (see Figure) and films are fully accounted for using a model based on linear excitonβphonon coupling and structural defects. In particular, the Davydov splitting is calculated to be of the order of 1 eV, and the unusua
