Figure 6.

The development of the twist-torque profile for increasing stretching force; the exerted torque τ is shown as a function of the twist Tw for various stretching forces f: (a) 0, (b) 200, (c) 800, and (d) 3200 kJmol⁻¹ nm⁻¹. The points in the graphs are individual data points. The darker lines are averages and the error bars represent the standard deviation around the averages. (e) Snapshots of the torsion simulation are shown, illustrating the conformation of the molecule at specific values of the twist Tw = −1, 0, 1 for f = 3200 kJmol⁻¹ nm⁻¹.
