摘要：
The phase diagram and electrical conductivity isotherms for the lithium tetrafluoroborate (LiBF4)–dimethylsulfoxide (DMSO) system and Raman spectra of DMSO and the LiBF4–DMSO solution were studied. Spectroscopic signatures of a H-bond between DMSO and BF4− ions were found. The bonds of Li+ ions to the solvent were stronger than the bonds in DMSO dimers because formation of the solvate destroyed dimeric DMSO molecules. The τω values for DMSO molecules in the Li+-ion solvate shell of the LiBF4–DMSO system were similar to those for associated solvent molecules.
