Fractional Spin-Labeling of Polymers for Enhancing NMR Sensitivity by Solvent-Free Dynamic Nuclear Polarization

Decapeptides are partly covalently labeled with a polarizing agent (see picture) to enhance NMR signals by dynamic nuclear polarization (DNP). DNP under magic angle spinning conditions at T=100 K was performed directly on these molecules in the absence of any solvent.
