MD-computed S ( q , E ) for MAPbBr 3 at 300 K for q = (H, 2.5, 1.5), which corresponds to a horizontal cut of the (H, K, L = 1.5) plane at K = 2.5. q with integer/non-integer H values correspond to M / R points in the Brillouin zone. Each vertical cross-section of c manifests as a quasi-elastic Lorentzian, centred at zero energy transfer.
