Abstract
The role of the solvent becomes critically important during ion transport when the electrolyte solute and solvent compete for coordination. Improved ionic conductivity requires ionic dissociation. The 'hip-hop' transition of the cations requires that ion pairs split and become solvated with solvent molecules during dissolution. To achieve these hopping transitions, lithium salts are the best choice. We have investigated the vibrational spectra of lithium nitrate and lithium triflate in two different non-aqueous organic solvents, namely THF and DMSO, through ATR-FTIR spectroscopy in order to investigate ion-solvent and ion-ion interactions, to learn more about solvents' lower and higher frequency vibrations, and factors affecting the identifiable characteristics, functioning, and interaction of ionic compounds with solvents.
