The experimental SAXS pattern of StOSt taken 6 min after the beginning of isothermal crystallization at 283 K after quenching from the melt (328 K) (frame 17, Fig. 1[link]) compared to the simulated SAXS pattern of the lamellar structure of StOSt with random stacking of 2L and 3L packing with the ratio of the amount of the 2L and 3L layers being 3:2 (β = 0.65) corresponding to a structure containing one half of the molecules packed in the 2L layers and the other half in the 3L layers (the patterns are presented on a logarithmic scale). The inset shows a set of simulated SAXS patterns (on a linear scale) with different coefficients of probability (β) corresponding to the amount of the 2L layers in the structure (β = 1 and β = 0 correspond to structures with 2L and 3L packing only, respectively). The simulated patterns have been obtained as an average over an ensemble of 100 particles where each particle contains in total 30 2L and 3L layers randomly distributed along the layer normal. The Miller indices are assigned to the lamellar peaks.
