摘要：

Nanodiamonds obtained by the detonation method have been investigated by means of solid-state magnetic nuclear resonance (NMR) and electron paramagnetic resonance. (13)C and (1)H magic angle spinning (MAS) NMR and (13)C MAS NMR with (1)H to (13)C cross-polarization allow the determination of surface-hydrogenated groups (CH, CH(2), and COH) and the quasi-absence of an sp(2) carbon fullerene-like shell on the diamond surface to be underlined. The (1)H and (13)C spin-lattice relaxation time (T(1)) and second moment measurements are presented as a function of the temperature. Relaxation is shown to be mainly caused by paramagnetic centers in the case of (13)C nuclei, whereas the presence of a molecular motion with an activation energy of 11.15 kJ center dot mol(-1) is involved for (1)H nuclei.
