This chapter is devoted to the study of the dynamic Jahn-Teller effect on the optical spectra of 3d-ions impurities in crystals, with particular attention to the theoretical efforts addressed to the interpretation of the experimental results. The presentation assumes that the reader is familiar with the spectroscopic notation for atomic energy levels. In addition, basic concepts and notation of point-group theory are also used. First, we will present a survey of the main experimental and theoretical results according to the electronic configuration. Then we discuss with a tutorial style the main contributions needed to model the optical spectra of the Jahn-Teller active 3d-ions impurities and asimple example is discussed in details. Next we concentrate on the calculation procedures required to address realistic systems.

Abstract
This chapter is devoted to the study of the dynamic Jahn-Teller effect on the optical spectra of 3d-ions impurities in crystals, with particular attention to the theoretical efforts addressed to the interpretation of the experimental results. The presentation assumes that the reader is familiar with the spectroscopic notation for atomic energy levels. In addition, basic concepts and notation of point-group theory are also used. First, we will present a survey of the main experimental and theoretical results according to the electronic configuration. Then we discuss with a tutorial style the main contributions needed to model the optical spectra of the Jahn-Teller active 3d-ions impurities and asimple example is discussed in details. Next we concentrate on the calculation procedures required to address realistic systems. Some applicative examples of the proposed procedure are described in details. © Tsinghua University Press, Beijing and Springer-Verlag Berlin Heidelberg 2013.
