Thirteen classical MD simulations of Motor S were initiated from metastable form ground state conformations available at the end of the QM surface-hopping simulations (Section 3.1), and each was run for a total of 1 µs. Because the surface-hopping simulations of Motor N did not yield any metastable conformations we could use to initiate classical MD (Section 3.1), for this motor we instead initiated four 1 µs classical MD simulations, one from each of the four metastable substates identified by the MSM (Section 3.3.2). No obvious pathologies were observed in the course of these simulations for either motor, and several interesting trends were observed.
