(a)–(c) Reconstructed diffraction patterns in (hk0) and (0kl) of α at 8 kbar, γ at 13 kbar and δ at 20 kbar, with diamond signals marked in cyan. Transition to a monoclinic system is gradual and already visible in the pattern of γ. (d) The δ (0kl) plane features partial extinctions characteristic for the nx glide plane; violations of such extinctions are only discernible at high resolution (inset, k = 12 and k = 14).
