摘要：
We have studied the depolarized Rayleigh-Wing light scattering of aqueous solutions of 2-butoxyethanol (C4E1) as a function of the temperature and concentration. The measured spectra give information on the rotational dynamics of water molecules. Their analysis confirm the amphiphilic character of the ethoxylated alcohol molecules that originates micellar structures. In addition, the water dynamics shows, in agreement with recent small angle neutron scattering measurements, the simultaneous presence of micelles and concentration fluctuations. This latters are dominant at high temperatures when one approaches the demixtion curve.
