Abstract

The infrared (IR) spectra of propylene carbonate (PC), gamma-butyrolactone (BL) and diethyl carbonate (DEC) in the presence of LiClO4 have been investigated. It is shown that the interactions between Li+ and these solvents occur on the oxygen atoms of the carbonyl of solvent molecules. On the other hand, spectral curve fitting for band shape of perchlorate anion shows the presence of ion association in these solutions.
