For aggregated hyl-5,5',6,6'-tetrachlorobenzimidazolocarbocyanine (TTB
C) adsorbed onto silica, we have ascertained that coherent optical dyn
amical processes play key roles in defining the temporal response and
spectral profile of the fluorescence. We have also determined which co
herent processes are involved in what might generally be termed excito
n-exciton annihilation. Additionally, we provide in the TTBC system a
concrete example of room temperature superradiance.
