Molecular Relaxation of Lithium Arsenic Hexafluoride in One-Two-Dimethoxyethane.

Abstract

Audiofrequency electrical conductivity, Raman Spectra, radiofrequency ultrasonic absorption and microwave dielectric permittivity of LiAsF6 in the solvent 1-2 Dimethoxyethane (DME) are reported. Electrical conductivity reveal the electrolyte to be associated to ion-pairs (KA equals 1x10 to the fifth power M to the -one). Raman Spectra of the symmetrical stretching mode of AsF6 suggest the ion to be 'spectroscopically free', namely either unpaired or solvent separated from the cation. Ultrasonic relaxation data are interpreted as due to the equilibrium Li(+), S, negative ion AsF negative reversible(negative ion to a positive Ion) 6 LiAsF6, S being a solvent molecule. The equilibrium appears to be heavily shifted toward the left, in accord with the information by Raman Spectra. (Author)
