"Theoretical NMR spectroscopy in solids"

I will give an introduction on how to model NMR chemical shifts [1] and quadrupole interactions [2] in solids using periodic boundary conditions, Density Functional Theory (DFT) and in particular our WIEN2k code[3]. I will discuss the accuracy and limitations of this approach [4] with an emphasis on understanding the origin [5] of the observed chemical shifts or quadrupole splittings. Finally I will show various examples starting from a series of very simple systems and moving on to rather complex materials, where the combination of experiment and theory can help to come to an unambiguous interpretation of the experiments.
