Spin‐diffusion solid‐state NMR measurements prove the existence of alkyl‐chain domains with different mobilities at C 30 reversed phases and give insight into the spatial distribution (see picture: region a: rigid, 32 Å; region b: mobile, 112 Å). A computerized simulation of the change in the signal during the spin‐diffusion experiment allows the determination of the areas of the alkyl‐chain cluster.
