A theoretical analysis of absorption and fluorescence in p-distyrylbenzene
(DSB) nanoaggregates is performed. The model Hamiltonian includes intramole
cular electron-vibrational coupling as well as excitonic coupling between m
olecules in a herringbone lattice. Excellent agreement with experiment is o
btained. (C) 2001 Elsevier Science B.V. All rights reserved.
