This paper reviews the results of many time-resolved fluorescence measurements upon vinyl(aromatic polymers) in dilute solution excited by picosecond lasers. The complex kinetics of excimer formation and decay in such polymers revealed by these measurements are discussed, and some preliminary results on the models for these polymers, the dinaphthyl propanes, presented. The kinetics of population and decay of a phenyl oxazole trap in poly(styrene) have been studied and results interpreted in terms of energy migration within the poly(styrene) system. Support for this contentious proposal is gained from measurements of nanosecond time-resolved fluorescence anisotropy.
