Abstract
- AbstractThe infrared (IR) and Raman spectra of propylene carbonate (PC) containing various concentrations of LiClO4have been measured and analyzed. The difference in spectra of PC with and without LiClO4was attributed to the interaction of the PC molecules and lithium ions. This interaction occurs mainly on the carbonyl oxygen atom of the PC molecule. The ring deformation, symmetric ring deformation, carbonyl stretching and stretching of ring oxygens for PC are sensitive to this interaction. The solvation number of Li+is also calculated. On the other hand, the structure of the ClO−4is also affected by PC molecule, forming the solvent separated ion pairs.
