Paper doi abstract bibtex A pulse sequence has been implemented for the determination of domain sizes in 13C enriched organic materials with two-dimensional high-resolution magic angle spinning (MAS) NMR correlation spectroscopy. The method integrates the high resolution of 13C MAS for selection and detection with an efficient polarization transfer across domain boundaries via strong 1H dipolar interactions. A one-dimensional version with spectral editing allows for improved efficiency with respect to measurement time. With this MAS NMR and labeling approach heterogeneity at length scales from 1 to 100 nm can be determined for systems without long-range order. As an example, proton spin diffusion times up to 500 ms were used to study the morphology of a phase-separated semi-interpenetrating network of poly(styrene-co-acrylonitrile) and cross-linked poly(styrene-co-maleic anhydride). From the spin diffusion behavior a characteristic domain diameter d = 63 ± 4 nm was calculated.
