摘要：
In the present paper, surface tensions and viscosities for DMSO aqueous solutions with volume concentration range from 5 to 100% and ultrapure water weremeasured by the ZL-10 Type surface tension instrument and NDJ-5S digital readout viscometer. Dependences of Raman shiftseffects of hydrogen bands on DMSO concentrationwere investigated. The results indicated that, surface tension was influenced by the hydrogen band behavior with variation of concentration, which has a reciprocal correlation with the hydrogen band intensity. The hydrogen band behavior between DMSO and water influenced viscosity more intricately, with viscosity having quadratic relationshipwith concentration. The influence factors include several aspects like the hydrogen band intensity and spatial directionality. We explored aexperimental method about using Raman spectrospcopy to investigate the relationship between microstsucture and macroscopic physical properities of aqueous solution.
