Diffusion-controlled interactions between small molecules, between              polymers, and between small molecules and polymers are studied by a             combination of fluorescence and phosphorescence quenching experiments           and excimer fluorescence.  These studies will yield information related         to polymerization kinetic parameters and, in particular, will allow for         an investigation of how various polymer solution variables such as              molecular weight, concentration, and polymer-solvent compatibility              control the onset of the 'gel' effect. Furthermore, these studies lead          to a greater fundamental understanding at a molecular level of polymer          diffusion processes, Rouse dynamics and dynamics of entangled polymers,         and the structure of polymer solutions.  Photophysical studies such as          fluorescence quenching are key to the success of this research.
