Single-chain structure factor. Static structure factor S(q) for a chain of length N _l = 100. a S(q) at x _c = 0.0 and (b) x _c = 0.7. In a, we also include the analytical expression for sphere scattering. In b, red and green lines are power law fits to the data at different length scales. The black line represents the Guiner region for q→0 (for large length scales). The vertical arrow indicates the effective Θ—blob size at q = q _Θ, estimated using ${\ell }_{\Theta -\mathrm{blob}}=2\pi \mathrm{∕}{q}_{\Theta }$. Note: to get a better estimate of the cross-over scaling regime, S(q) is calculated from a simulation of a chain length N _l = 100
