Dissociation of C6F5SO3Li in two organic solvents with different dielectric constants: a Raman spectroscopic study

Résumé

Organic solutions of lithium pentafluorobenzene sulfonate (C6F5SO3Li) with varying molalities in N,N-dimethyl formamide (DMF) and triethyleneglycol dimethylether (triglyme) were investigated by Raman spectroscopy. Spectral decomposition in the νs(SO3) stretching region showed bands characteristic of free anions, ion pairs and various aggregates. The relative fraction of each species has been followed as a function of salt molality. In DMF, free anions dominate, while in triglyme ion pairs dominate, in accordance with the solvent dielectric constant.
