The precedent book with the title "Structural Analysis of Point Defects
in Solids: An introduction to multiple magnetic resonance spectroscopy"
ap- peared about 10 years ago. Since then a very active development has
oc- curred both with respect to the experimental methods and the
theoretical interpretation of the experimental results. It would
therefore not have been sufficient to simply publish a second edition of
the precedent book with cor- rections and a few additions. Furthermore
the application of the multiple magnetic resonance methods has more and
more shifted towards materials science and represents one of the
important methods of materials analysis. Multiple magnetic resonances
are used less now for "fundamental" studies in solid state physics.
Therefore a more "pedestrian" access to the meth- ods is called for to
help the materials scientist to use them or to appreciate results
obtained by using these methods. We have kept the two introduc- tory
chapters on conventional electron paramagnetic resonance (EPR) of the
precedent book which are the base for the multiple resonance methods.
The chapter on optical detection of EPR (ODEPR) was supplemented by
sections on the structural information one can get from "forbidden"
transitions as well as on spatial correlations between defects in the
so-called "cross relaxation spectroscopy". High-field ODEPR/ENDOR was
also added. The chapter on stationary electron nuclear double resonance
(ENDOR) was supplemented by the method of stochastic END OR developed a
few years ago in Paderborn which is now also commercially available.
