Abstract: A high resolution solid state DNP CP/MAS probe was designed.By using this probe,high resolution NMR spectra of solid state samples containing free radicals were obtained.Some typical results are shown in this paper. Technical problems in DNP NMR experiment are discussed and some methods are suggested to deal with these problems.

Key words: DNP, Solid state high resolution NMR, CP/MAS
