Abstract

Recently, reversed micelles (“water-in-oil” microemulsions) have found interest in EPR and ENDOR spectroscopy because they offer the unique potentiality to study water-soluble radicals in the water pool without strong microwave absorption.1 Using spin label techniques, information about molecular properties, structural organisation and dynamic behaviour of nitroxide spin probes in the reversed micelles could be obtained.2 We have demonstrated the suitability of semiquinone radical anions for EPR and ENDOR studies in reversed micelles. Important information about the interaction between the radicals and the water-surfactant interface was accessible.3
