摘要：
We have examined by C-13 solid-state NMR crystalline quality of cubic diamond produced either via firing of explosive compositions, or through compression of mixtures containing carbonaceous precursors with metallic matrix. In particular MAS technique was used to estimate sp(3)/sp(2) phases ratios for the obtained condensed carbon, whereas functionality of surface carbon atoms was studied rather via CP-MAS method.
