In-Situ Electron Spin Resonance and Voltammetric Studies Using an Internal-Flow-Type Electrolysis Cell

Abstract

A newly designed three-electrode electrolysis cell for in-situ electron spin resonance (ESR) spectroscopy and cyclic voltammetry is described. An electrolysis solution near the electrode surface is continuously renewed by an internal-flow method, which makes it possible to record the well-resolved ESR spectra of unstable free radicals. An accurate control of the electrode potential using an ohmic drop corrector has enabled us to obtain a fairy good
voltammogram. This cell can be applicable to both oxidation and reduction experiments in aprotic and protic media at an arbitrary temperature by the use of a temperature-controlled Dewar vessel. Some fundamental experiments are reported.
