Computed values of the torsional moment in the molecule M_ext as a function of the pulling force F_ext. We compare the results of this model using the interaction potentials U_PB, $U_{\text{PB}}^{†}$ or U_CC, to predictions in Marko (20), namely Marko's Eq. 17 with A = 50 nm, C = 95 nm, and P = 28 nm, and Strick et al. (42), and results from our previous work (9).
