Paper Abstract

The role of dielectric friction in solvation dynamics and rotational motion is examined. Using the connection between solvatiOn dynamics and time dependent dielectric friction developed by van der Zwan and Hynes, it is demonstrated that solvation times determined from time dependent fluorescence studies can be used to accurately gauge dielectric friction contributions to the rotational diffusion of an oxazine dye in alcohol solutions. The generality of these conclusions requires that additional probe molecules, spanning a large range of permanent dipole moments, be studied. A series of amino substituted fluorenones are shown to be an excellent choice of molecules for such studies.
