Query: The Influence of a Pitchfork Bifurcation of the Critical Points of a
  Symmetric Caldera Potential Energy Surface on Dynamical Matching   Many organic chemical reactions are governed by potential energy surfaces
that have a region with the topographical features of a caldera. If the caldera
has a symmetry then trajectories transiting the caldera region are observed to
exhibit a phenomenon that is referred to as dynamical matching. Dynamical
matching is a constraint that restricts the way in which a trajectory can exit
the caldera based solely on how it enters the caldera. In this paper we show
that bifurcations of the critical points of the caldera potential energy
surface can destroy dynamical matching even when the symmetry of the caldera is
not affected by the bifurcation.
