F-19 NMR spectroscopy and conductometry were used to study solutions of lit
hium tetrafluoroborate in water, propylene carbonate, gamma-butyrolactone,
1,2-dimethoxyethane, and tetrahydrofuran within a wide range of concentrati
ons at 25 degrees C. It is proposed that in solvents of low polarity the in
terparticle interactions become more complex, and particles, including ions
, ion associates, and solvent molecules are present. (C) 1999 Elsevier Scie
