In the E.S.R. spectra of K pyrazine in dimethoxyethane asymmetries are observed which are attributed to second order shifts of the nitrogen hyperfine lines. From a detailed analysis of the line shapes it follows that these shifts should be attributed to an ion pair in which the potassium ion is localized symmetrically with respect to the two nitrogen nuclei. The E.S.R. spectra cannot be explained by migration of the cation between two equivalent sites. The spectra at low temperatures indicate the presence of a rapid exchange reaction between the contact ion pair and a solvent separated ion pair.
