英文摘要	Four I-b-type synthetic diamond crystals were studied by dynamic nuclear polarization (DNP)-enhanced high resolution solid state C-13 nuclear magnetic resonance (NMR) spectroscopy. The home built DNP magic-angle-spinning (MAS) NMR spectrometer operates at a field strength of 1.9 T and the highest DNP enhancement factor of synthetic diamonds came near to 10(3). Comparing with I-b-type natural diamonds, the C-13 NMR linewidths of synthetic diamonds in static spectra are broader. The C-13 spin-lattice relaxation time and DNP polarization time of synthetic diamond are shorter than those of I-b-type natural diamond. From the hyperfine structure of the DNP enhancement curve, four kinds of nitrogen-centred free radicals could be identified in synthetic diamond.
