Quasielastic neutron scattering was used to study the motions of mono
end-brominated alkyl chains included in channels of C9H16NO2 (tano). B
y using powdered and crystalline samples and several spectrometers, it
was possible to analyse individually ring inversion of tano, 120 degr
ees jumps of its methyl groups and the anisotropy of the motions of th
e guest chains. Recent molecular simulation results are also briefly m
entioned.
