We report on investigation of detonation nanodiamond annealed at 800 degrees C in chlorine atmosphere by means of H-1, C-13 and Cl-35 nuclear magnetic resonance and X-ray photoelectron spectroscopy. The results of these methods are found to be consistent with each other and evidence formation of chlorine-carbon groups and sp(2) carbon shell on the nanodiamond surface. The data obtained provide detailed information about the structure and bonding in this diamond nanoparticle. Interaction of nuclear spins with unpaired electron spins of dangling bonds results in fast C-13 nuclear spin-lattice relaxation.
