| Abstract
| - Time-resolved optical Kerr effect spectroscopy has been used to probe the molecular environment affordedby the hydrophobic core of oil-in-water microemulsions. This was achieved by measuring the ultrafastdynamics of a series of benzene derivatives (benzonitrile, nitrobenzene, fluorobenzene, styrene, and toluene)incorporated as the oil phase within oil-in-water microemulsions and comparing them to the dynamics inneat liquid and the liquid diluted in nonpolar solvent. Polar and strongly interacting liquids (benzonitrileand nitrobenzene) showed dynamics in the microemulsion that are similar to those in the solution phase,while weakly interacting and mildly polar liquids (fluorobenzene, styrene and toluene) reveal dynamicsmore similar to those of the neat liquid. This suggests stabilization of the polar dispersed phase in polarregions of the micelle.
