Origin of Linewidth Alternation in Semiquinone–Alkali Metal Systems


THE electron spin resonance spectra of semiquinone–alkali metal systems in 1,2-dimethoxyethane (DME) have recently been interpreted1 in terms of (a) two types of ion-pair, A or solvated type and B or contact type, which appear separately or together depending on the temperature and (b) an equilibrium between these two types of ion-pair which is thought to be the cause of marked line-width alternation. We have also studied these systems over a wide temperature range, but have drawn quite different conclusions.
