Figure 1.

Schematic representation of the correlation function $G\left(\mathit{r}\right)$ in real space and the structure factor $S\left(\mathit{q}\right)$ in reciprocal space for one-dimensional systems with long-range order (a,b) and short-range order (c,d). Due to the exponential decay of the envelope of the correlation function in the case of short-range order (c), only one broad Lorentzian-shape peak is visible in the structure factor (d).
