24. 2 was calculated from eq 10, which used the first intercept of the zero correlation function (B value). The effect is clearly shown in Figure 3, where correlation function profiles, created from the Lorenz-corrected intensity data at 60°C, are disclosed. At the beginning of the crystallization, the secondary background peak caused a shift of the first minimum in the correlation function to smaller values on the distance scale. However, during the initial stage of crystal growth, the intensity of the long-period peak substantially increased and gradually overlapped the weaker secondary shoulder. This long-period-peak growth resulted in the shift of the correlation function minimum back toward larger distances.
