Spectral diffusion in glycerol–water mixtures from theoretical two dimensional infrared spectroscopy: varying effects of concentration for different solvation environments
Abstract
≈ 0.075. A similar change in the dynamics is also observed for orientational relaxation of trapped water molecules at the same glycerol concentration, which we refer to as the cross-over concentration for these mixtures. The dynamics of bulk water and also of those in the hydration shell of a single glycerol molecule are found not to exhibit any such crossover with increase of glycerol concentration. The distinct dynamical behavior of trapped water with variation of glycerol concentration can be linked to the glycerol induced effects on the dynamics of water-water hydrogen bonds.
