Сalculation for infrared vibrational spectrum of bis-adduct C$_{60}$ (C$_6$H$_{14}$N$_2$O$_2$)$_2$

The C$_{60}$ adduct with lysine was synthesized using a heterogeneous liquid-phase non-catalytic reaction. The identification was carried out by High perfomance liquid phase chromatography, electron and infrared spectroscopy, and complex thermal analysis. The formula of the synthesized crystal-hydrate was determined as: C$_{60}$ (C$_6$H$_{14}$N$_2$O$_2$)$_2$ $\cdot$ 5H$_2$O. A good agreement between the experimental and calculated data on the wavenumbers of the valence vibrations of the OH-groups (3460 and 3446 cm$^{-1}$) and the deformation vibrations of the COH (1446, 1441 cm$^{-1}$) allowed us to conclude that lysine-fullerene binding in the $\varepsilon$-NH$_2$ position is preferable.
