Modern diffusion-ordered NMR spectroscopy in chemistry of supramolecular systems: the scope and limitations

The concept of diffusion-ordered NMR spectroscopy (self-diffusion coefficients measurement in high-resolution mode) is considered. The most important aspects of interpretation of experimental data, as well as the scope and limitations of the available theoretical and phenomenological models relating the self-diffusion coefficient to the size or mass of the molecular system are discussed.
