Course objectives:
|
The course "Methods of studying the structure of substances I" introduces students to the basic methods for studying of the structure of such substances. These are infrared and Raman spectroscopy, electronic spectroscopy in the UV-VIS-NIR region, selected methods based on the interaction of matter with magnetic field (magnetochemistry, ESR, solid-state NMR) and thermal analysis. For each method, students are introduced to the theoretical basis of the experimental technique and then followed by practical exercises.
