A review. Different exptl. approaches for the application of NMR spectroscopy to dispersed nanoparticles are summarized and briefly discussed regarding their specific advantages and disadvantages. A general numeric approach for the anal. of the obtained data is introduced which accounts for rotational and lateral diffusion of the particles in a fluid medium. The applicability of the NMR expts. together with the numerical anal. of the resulting spectra is demonstrated on various examples which cover the particle structure, phase transitions, decompn. pathways, mol. exchange at phase boundaries, and release processes.
