The heat capacity Cm of polycrystalline fullerite C₆₀ doped with nitrogen has been measured in
the temperature interval 2–13 K. The contributions to the heat capacity from translational lattice
vibrations (Debye contribution), orientational vibrations of the C₆₀ molecules (Einstein contribution),
and from the motion of the N₂ molecules in the octahedral cavities of the C₆₀ lattice have
been estimated. However, we could not find (beyond the experimental error limits) any indications
of the first-order phase transformation that had been detected earlier in the dilatometric investigation
of the orientational N₂–C₆₀ glass. A possible explanation of this fact is proposed.
