Neutron scattering study of molecular motions in solid C_(60) intercalated with O_2 and N_2

摘要

Structure and dynamics of polycrystalline C_(60) intercalated with O_2 and N_2 have been studied. With exception of a general lattice expansion the influence of guest molecules on the C_(60) matrix is small. Vibrations of intercalated molecules are well localized but, a broad distribution of librational modes indicates considerable orientational disorder.
