| Abstract: | The elastic, quasielastic and inelastic structure factors for neutron scattering on CH3 groups tunnelling in a sinusoidal hindering potential with threefold symmetry are calculated as a function of the momentum transferQ. A comparison is made with data on methyl groups in nitromethane obtained with high resolution inelastic neutron scattering experiments at high momentum transfer. |
