Abstract
Steady-state and time-resolved optical techniques are employed to measure the solvation static and dynamics of large probe molecules in small polyethers. In ethylene glycol dimethyl ethers (n = 2, 3, and 4) we find that the solvation dynamics span from ∼50 fs to more than 100 ps. Three major time components can be resolved. The short time is bimodal with an ultrafast Gaussian component 100 ps is ascribed to cooperative motion of the polymer matrix.
