摘要：

IR-spectra of a great number of samples of detonation nanodiamonds (DND) obtained under different conditions (with dopants added or with the use of reducing agents) have been analyzed for the first time. The quantity and type of incombustible impurities have been found to have no effect on the pattern of IR spectra. It is shown that in the IR-spectral range there exist some narrow frequency ranges where the majority of DND exhibit absorption regardless of the synthesis conditions (829, 1365, 1558, 1628, 1732, 2341, 2858, 2928 cm(-1)). IR-spectra confirm the presence of nitrogen impurity centers in new DNDs and of the functional groups NO2, CH, NO3, CH2, OH, C=O on the DND surface.
