Figure 6
Displacements along x of the Cr, O2 and O3 atoms as a function of t. The discontinuities in the modulation of O2 and O3 occur at the same t = 0.944, but the discontinuity of the Cr atom (t = 0.930) is slightly shifted. The two discontinuities in the curve for O2 are symmetrically related. Symmetry codes: (i) , , 1-x3, -x4; (ii) , , 1-x3, . |
