Abstract
Various harmonic theories of classical solvation dynamics in glassy systems are discussed. The “optimized normal mode” theory is found to provide a substantial improvement over more standard normal mode approaches for the description of solvation dynamics in both glassy and supercooled media. A methodology is developed to include all multiphonon terms in the expansion of the collective solvation coordinate, thus going beyond “linear” solvation theories. The results suggest that the methods described here can provide a quantitative description of solvation over a wide temperature range in systems of low diffusiveness. Lastly, the extension of Zwanzig’s model of self-diffusion in supercooled media to the treatment of solvation phenomena is discussed.
