    Annotation An intriguing property of the multistep magnetization transfer, so-called spin diffusion, is that it can affect the results of NMR-based analysis of conformer distribution of small molecules in solution. Therefore, the contribution of spin diffusion should be subtracted in order to obtain accurate data on molecular conformations and their distributions. Several methods have been developed for this purpose, but many of them have a lack of versatility. These methods were critically analysed, and two approaches to eliminate spin diffusion were tested during the study of felodipine as the drug molecule of small size. QUIET-NOESY was found to be a powerful technique to solve this problem. The second method, combined analysis of two sets of spectra, NOESY and T-ROESY, was tested and proved to be the most correct way of obtaining exact internuclear distances in a flexible molecule in solution. ? 2015 Elsevier B.V.
