Reaction coordinate switching is a sudden switch between a reaction coordinate and a non-reactive coordinate triggered by a breakdown of a normally hyperbolic invariant manifold located in a vicinity of a reaction barrier. This phenomenon occurs only in systems with more than two degrees of freedom and thus it adds several novel features that cannot be seen in bifurcations of periodic orbit dividing surfaces in two-degrees-of-freedom systems. Moreover, it is also expected to be applicable in controls of chemical reactions. In this talk, we propose several methods to analyze the phenomenon. In addition, we address a possibility of its experimental verification and also its quantum manifestations in a hydrogen atom in crossed electric and magnetic fields. H. Teramoto, M. Toda and T.
