ELECTRON PARAMAGNETIC RESONANCE STUDIES OF ION PAIRS - KINETICS OF INTERCONVERSION BETWEEN DIFFERENT ION PAIRS AND RAPID ELECTRON-TRANSFER REACTION BETWEEN ANION AND NEUTRAL MOLECULE

Kinetics of the interconversion between a tight ion pair and a loose ion pair were studied in detail. The rate constants, activation energies, and the entropy of activation for interconversion of ion pairs are determined for sodium naphthalenides in the mixtures of tetrahydrofuran and diethyl ether. The equilibrium properties of the same system are also discussed. The rates of electron-transfer reactions between radical anions and neutral molecules were studied in a variety of naphthalenide systems. The rates are discussed in terms of the ion-pair equilibria, described in the first part of the paper, and the connection between the ion-pair structure. Activation energies and preexponential factors for electron-transfer reactions were determined for many naphthalenide systems. © 1968, American Chemical Society. All rights reserved.
