Molecular aggregates are well known for their customizable optical properties.
Vibronic coupling in monomers forming such aggregates offers rich opportunities for property
tuning. We study generic molecular aggregate models of growing complexity (from a dimer up to
a decamer) and report how vibronic coupling affects aggregate fluorescence intensity. The total
aggregate fluorescence intensity is a measure sensitive to both vibronic coupling and Coulomb
coupling between monomer transition densities. Using an exact diagonalization approach in
the two-particle basis set, we show how the interplay between Coulomb and vibronic coupling
affects aggregate fluorescence. Moreover, for H-aggregates we predict a periodic variation of
the fluorescence intensity with aggregate size and show that vibronic interaction decreases the
effect.
