A novel mechanism for inducing oriented processes is investigated with a flexible system exhibiting barrier-overcoming dynamics. Without any external switching of potentials, multidimensional flexible dynamics promote the oriented processes under nonequilibrium conditions, where reaction paths deviate from those at equilibrium with an accompanying violation of symmetry between the forward and the reverse paths. Along each path, distinct bottleneck points are proposed as a rate-controlling factor. The direction-dependent activation energies evaluated from the actual potential energies at these points are found to satisfy Arrhenius-like law for the rate constants.
