Abstract

The paper is devoted to the measurements of one-electron redox potentials of transient free radicals E^o. These values can be measured in the reversible redox reactions of radicals under investigation with a reference pair, which E^o is known. Several E^o of transient radicals are presented. The convenient and important objects for E^o measurement are quinone/semiquinone radical-anions. A general problem of measurement of thermodynamic properties of short-lived transients is discussed.

测量自由基的单电子氧化还原电位

本文致力于测量瞬时自由基 Eo 的单电子氧化还原电位。这些值可在自由基的可逆氧化还原反应中通过已知 Eo 的参比对进行测量。本文介绍了几种瞬态自由基的 Eo。方便测量 Eo 的重要对象是醌/半醌自由基阴离子。讨论了测量短寿命瞬态热力学性质的一般问题。
