Investigation of the solvation's processes of the ions in non-aqueous solutions by IR spectroscopy

IR spectra of solutions of LiCIO₄ (1), NaCIO₄ (2), LiI (3), NaI (4) in binary acetone — acetonitrile solvent were investigated in the region of CN (1–4), CC (1,3) and CH (3,4) stretching vibration bands of acetonitrile and CCC group (1) asymetric stretching vibration band of acetone at the wide range varying of the composition of the binary solvent. Infrared studies were also carried out on solutions of LiCIO₄ and NaCIO₄ in CH₃CNC₂H₅OH mixtures. The C N (1,2) and CC (1) stretching bands of acetonitrile were measured for 0.7–1.0M of CH₃CN. The observed intensities of IR bands allowed to calculate the solvating abilities of used solvents and to estimate the change of solvation sphere composition.
