EPR techniques applied to the study of chemistry and catalysis on oxide surfaces

The use of electron paramagnetic resonance (EPR) spectroscopy to study the chemistry of oxide surfaces and catalysis is discussed. Emphasis is placed on those aspects of tire techniques that are directly related to the specif icity of heterogeneous systems, investigations of surfaces and catalytic re actions. The characteristic features of EPR spectra of high-surface oxide m aterials are analyzed, and the typical means employed to increase the amoun t of extractable information are presented. A brief survey of new potential ities of continuous-wave EPR and typical applications is also provided.
