We report direct [superscript 13]C dynamic nuclear polarization at 5 T under magic-angle spinning (MAS) at 82 K using a mixture of monoradicals with narrow EPR linewidths. We show the importance of optimizing both EPR linewidth and electron relaxation times by studying direct DNP of [superscript 13]C using SA-BDPA and trityl radical, and achieve [superscript 13]C enhancements above 600. This new approach may be best suited for dissolution DNP and for studies of [superscript 1]H depleted biological and other nonprotonated solids.
