High-Field (13)C Dynamic Nuclear Polarization with a Radical Mixture
From the The DNP-NMR Blog:
High-Field (13)C Dynamic Nuclear Polarization with a Radical Mixture Michaelis, V.K., et al., High-Field (13)C Dynamic Nuclear Polarization with a Radical Mixture. J Am Chem Soc, 2013. http://www.ncbi.nlm.nih.gov/pubmed/23373472 We report direct (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 (13)C using SA-BDPA and trityl radical, and achieve (13)C enhancements above 600. This new approach may be best suited for dissolution DNP and for studies of (1)H depleted biological and other nonprotonated solids. Go to the The DNP-NMR Blog for more info. |
