Inelastic neutron scattering has been used to study the tunnelling of methyl groups belonging to several guest molecules (toluene, p-xylene, 7-picoline) incarcerated in a host calixarene matrix. In all the cases investigated, the low temperature neutron spectra show a number of bands which may be in
