The results of simulations of rotational diffusion effects in systems with and without orientational order. The amplitudes of the FCs [| \langle C_{ii}^{n} (q_{1}, q_{2}) \rangle_{i} |] for n = 2, 4 and 6 at q2 = 0.25 nm−1 are shown. In the model of a mixed system of particles, a fraction of the particles have a Gaussian distribution of orientations about the xz plane (GaussXZ) with σxz = 2.0, while all other particles obey a uniform distribution (Unif), where the corresponding fractions are specified in the figure legends. The results of simulations with rotational diffusion are compared with those without rotational diffusion [shown in Fig. 9[link](a)]. The difference between panels (a) and (b) is in the distinct number of X-ray snapshots, (a) ten versus (b) 20, averaged to form individual averaged diffraction patterns, when simulating rotational diffusion effects (see Appendix E[link]).
