The excitation spectrum of solid methane (CH 4 ) with all molecules converted to the nuclear spin state with A symmetry has been measured with incoherent inelastic neutron scattering. For energies [Formula: see text], there are no dramatic differences with samples consisting of a mixture of all three spin states A, T, and E. A qualitative understanding of the measurements is achieved by comparison with calculations of Ozaki et al.
