Orientation of the vinyl group. (a) Torsion angle C02—C03—C10—C11 as a function of the modulation parameter t. (b) Fourier map for atom C10 in the x2–x4 plane, refined in (3+1)-dimensional superspace. For clarity, two periods are shown along the fourth dimension. In addition, the values found in the superstructure approximations are superimposed. |
