Electron spin resonance -active paramagnetic species

The chapter Electron Spin Resonance in Catalysis by Lunsford was prompted by the extensive activity in this field since the publication of an article on a similar subject in Volume 12 of this serial publication. This chapter is limited to paramagnetic species that are reasonably well defined by means of their spectra. It contains applications of ESR technique to the study of adsorbed atoms and molecules, and also to the evaluation of surface effects. The application of ESR to the determination of the state of transition metal ions in catalytic reactions is also discussed. 

Electron spin resonance (ESR) is a sensitive spectroscopic method for the investigation of local crystal structure and electronic properties of paramagnetic species in materials. Such species carrying the magnetic moments are often employed as active electrode materials for lithium-ion batteries and their electrochemical properties substantially determined by their structural features. In this chapter, application of ESR method to study the electronic structure of layered and NASICON structured cathode materials is presented.
