Four constant Q cuts through Fig. 3 (red line) and Fig. 7 (black line) for a Q bin of width of 0.067 Å−1. The horizontal axes are energy transfer and vibrational frequency (meV and cm1, respectively) and the vertical axis is S′coh(Q, ω). Major scattering features are labelled for each cut in terms of a point along the direction in the conventional reciprocal lattice [hkl]. Red arrows (below spectra) denote an identified feature, with appropriate [hkl], in the LJ 12–6 theoretical data and black arrows (above spectra) the equivalent feature in the MARI data. Relative intensities between cuts are not to scale, for clarity of presentation.
