Courses
Physics (M.Sc.) 12PHYMWPMQ2
The main goals of this course, composed of the lectures and seminars, are to give:
 an overview of various applications of nuclear magnetic resonance (NMR)
 basics of nuclear magnetic relaxation processes
 insights into diffusion processes and diffusion measurements in softmatter systems using gradient NMR
 basic understanding of magnetic resonance imaging (MRI)
 first onhand experience with experimental NMR
The module is recommended for M.Sc., B.Sc. IPSP and M.Sc. IPSP students.
