英文摘要：

In the present paper, DMSO/H2O,Acetone/H2O and ACN/H2O mixtures are measured by Raman spectroscopy. In addition, the optimized structure of DMSO/H2O,Acetone/H2O and ACN/H2O mixtures are calculated using MP2. The results showed that the hydrogen bond strength in three aqueous solutions are in the order,DMSO/H20 〉 Acetone/H2O 〉 ACN/H2O. The theoretical calculations are in good agreement with the experimental results. The research provides experimental basis for aqueous hydrogen bonding theory.
