Ultra‐fast : Substantial solid‐state NMR sensitivity can be achieved using dynamic nuclear polarization and matrix‐free sample preparation (that is, absence of solvent and cryoprotectant). This method avoids line‐broadening, maximizes sample filling factor, and allows natural‐abundance 2D 13 C– 13 C dipolar correlation experiments to be carried out in tens of minutes. MW=microwaves.
