Abstract：In the present paper, the frequency shift and line widths of acetonitrile/H2O, DMSO/H2O and acetone/H2O aqueous binary solutions at different concentration were measured by Raman spectroscopy. The experimental results were analyzed by mixture model and empirical formula of line widths. The results show that the stronger the hydrogen bond interaction, the greater the line widths of Raman spectra in the three aqueous binary solutions; the line width of Raman spectra not only is affected by concentration fluctuation, but also is affected by hydrogen bond. In addition, the experimental data points are again nicely fitted using the empirical formula.
