摘要: The solvation dynamics of methanol has been investigated using a femtosecond time-resolved fluorescence up-conversion technique. Transient spectra Coumarin 152A dissolved in at different time were reconstructed from the measured decays. Stokes shift was obtained and solvent response function Sv(t) fitted bimodal with fast Gaussian component slow bi-exponential component. attributed to effect free streaming motion molecules, whereas caused by rotational diffusion molecules. A comparison our results reported data made.
