A Comprehensive Model for Molecular-Bond Formation and Rupture

Force spectra of ten different kinds of molecular bonds show transition from near-equilibrium to a kinetic regime. Inset, data re-plotted on the natural axes that emerge from the model show that it provides a universal description of bond breaking across the two regimes.
