✦ Synopsis

The selectivity of salvation with lithium cation was discussed in LiClO,/ethylene carbonat'e (EC)~propylene carbonate (PC), LiClO,/EC-H,O, and LiClO,/EC-CHCI, based on the results of Raman intensity measurements. The fundamental parameter for this analysis has been already determined on the ring breathing Raman band of EC. Following from this parameter, the results of the analysis showed that H,O molecules solvate to lithium cation selectively in LiClO,/EC~H,O system while EC molecules solvate to lithium cation selectively in LiClO,/EC-CHCI, system, as was expected previously. On the other hand, the results showed an ideal non-selective salvation of lithium cation in LiCIO,/EC~PC system.
