Electron magnetic resonance of aromatic radicals on metal oxide surfaces

  • Part II: Structure And Reactivity Of Radicals On Surfaces
  • Published:
Molecular Engineering

Abstract

Multi-frequency electron magnetic resonance (EMR) methods provide a powerful approach to the study of radicals adsorbed on metal oxide surfaces. The structure, adsorption characteristics, surface environment, and mobility of surface species often can be determined. In this review, EMR studies of radicals produced on oxide surfaces from polynuclear aromatic hydrocarbons, nitroaromatics, and sulfur-containing aromatics are considered. Intra- and intermolecular spin interactions are probed by techniques which emphasize Zeeman or non-Zeeman interactions, and couplings between unpaired electrons and nuclei such as1H,14N,17O,25Mg, and27Al are discussed.
