Abstract

Electron Paramagnetic Resonance (EPR) spectra can be measured in unperturbed crystals which contain paramagnetic ions or molecules as constituents, such as CUSO4 with paramagnetic Cu++ ions, and in crystals containing paramagnetic defects. In this chapter, typical EPR spectra of defects will be discussed in view of the application of multiple magnetic resonance methods to be discussed later. It is the purpose of this chapter mainly to discuss which kind of structural information can be obtained from the EPR spectra. Particular emphasis is given to a discussion of the EPR line width and its origin. It will be seen later, that the structural information from the EPR spectra is needed for an unambiguous analysis of the ENDOR spectra. We must restrict the discussion to “typical” spectra, in the sense that only those interactions of the unpaired electrons or holes which often occur are discussed, and the discussion is limited to simple quantum mechanical solutions of the Schroedinger equation. There is such a variety of possible spectra that a more comprehensive discussion would be beyond the scope and intention of this book (for more information see textbooks on EPR quoted in Chap. 1).
