Paper Abstract

The results of Raman spectroscopy research of aqueous ethanol solutions with various mixing ratios are presented. The analysis of the behavior of Raman spectra with changes in ethanol concentration from 0 to pure ethanol is given. The analysis of contour of stretching OH-band provided information about changes in hydrogen bonding along with increases in ethanol concentration. Obtained results showed that the maximum strength of H-bonding in aqueous ethanol solution corresponded to an ethanol concentration of 15...20 % w/w. The observed strengthening of H-bonding strongly supports the hypothesis of clathrate-like structures. These results were supported by application of MCR-ALS method.
