Solid state nuclear magnetic resonance can be an ideal method for local structure investigation. All nuclei, that possess a magnetic moment (I > 0), are able to provide detailed information about their local environments as local probe e.g., about bond angles, neighbouring atoms (1st and 2nd coordination sphere), the local symmetry, the coordination number, as well as being sensitive to dynamic processes. This is due to the fact that, beside the outside static magnetic field, there are small internal local fields that contain the appropriate structural information, which influence the effective magnetic field at the nucleus. The two most important interactions in this context are the chemical shift interaction for all nuclei and the electric quadrupolar interaction for nuclei with a nuclear spin of I > 1/2. In conclusion, NMR spectroscopy will be a powerful complementary method to X-ray structure analysis probing short range structural effects rather than long range order and many other methods used in mineralogy and geosciences.
The course pursues the goal to give undergraduate students, diploma students and PhD-students graduating in mineralogy / geosciences an introduction into the area of Solid NMR spectroscopy. Apart from teaching the necessary theoretical background, the course focuses on the application possibilities and strengths of the NMR spectroscopy for simple examples in the mineralogical research.
Each course day is divided into an introduction into theory, which is needed for the experiments carried out that day, subsequently evaluated by the participants afterwards.
The official Course Language is German!
