摘要：

The time-resolved dynamics of non-polar solvation have been measured in n-butylbenzene, a glass-forming liquid, through a combination of transient hole burning and time-resolved fluorescence. The solvent relaxation is highly non-exponential within the temperature range examined, 155-250 K. The average solvent relaxation times are equal to the average shear relaxation times, suggesting that the relaxation is primarily mechanical in nature. In support of this conjecture, a simple viscoelastic-continuum model of the solvent is developed that reproduces the basic features of the data.
