The course focuses on advanced methods of infrared, THz and MW spectroscopies, which will be taught with a common theoretical background. At the same time, advanced experimental methods will be discussed to distinguish high-resolution spectroscopy from other spectroscopies. Simultaneously with the theoretical interpretation, practical demonstrations in specialized laboratories of the University of Chemistry and Technology and of the Academy of Sciences of the Czech Republic will take place.
