摘要：

A new model for solvation dynamics based on the mechanical response of a continuous, viscoelastic solvent to the difference in the sizes of the ground and excited states of a solute is presented. In agreement with experiment, responses are predicted on two timescales: a subpicosecond 'inertial' response and a slower'diffusive' relaxation. Previous time-resolved Stokes shift data on dimethyl-s-tetrazine in n-butylbenzene [J. Chem. Phys. 99 (1993) 8552] are fit quantitatively. The subpicosecond response is predicted to have an approximate to 100 fs decay followed by a weak oscillation.
