Raman spectra were obtained for aqueous solutions of MgCl 2 , Mg(NO 3 ) 2 , MgSO 4 and Mg(ClO 4 ) 2 in both liquid and glassy states. Spectral changes associated with the transition from the liquid to the glassy state were studied for the Raman OH stretching spectra, and the restricted translational Raman bands of the low‐frequency Raman spectra of the glassy solutions were characterized. It is shown that the spectral features and peak frequencies are greatly dependent on the chemical natures of the anions.
