The DNP-enhanced NMR experiment was performed on the DBF samples doped with free radicals. The experimental results show that it becomes very easy to perform the complicate NMR experiments under DNP enhancement. For the sample whose spin lattice relaxation is very slow, if it is doped with appropriate quantity free radicals.

Key words: Free radicals, Nuclear maguetic resonance, Dynamic nuclear polarization
