| Abstract: | The influence of ions with different hydration properties on the stretching, bending, and low-frequency bands of water Raman scattering spectra has been investigated. The obtained results are explained using the ion hydration theory: from the point of view of the formation of hydration shells, ion pairs and complexes, and the migration of protons in water. Using the detected peculiarities of the dependences of spectra characteristics on the salt concentration for the determination of the parameters of long-range and short-range hydration is proposed. |
