Abstrakt: As a result of an experimental study of the Raman scattering valence bands of water in aqueous suspensions of detonation nanodiamonds with different functional surface groups, the energies of hydrogen bonds in suspensions of nanoparticles were calculated for the first time. It is shown that the degree of influence of different functional surface groups of nanodiamonds on hydrogen bonds in aqueous suspension decreases in the series H > polyfunctional surface > OH > COOH. The obtained data are confirmed by modeling of optimized nanodiamond structures in water clusters and theoretical calculations of the bond parameters in these structures by the density functional theory.
