The Time Evolution of the Trajectories After the Selectivity in a Symmetric Potential Energy Surface with a Post-transition-state Bifurcation

Selectivity is an important phenomenon in chemical reaction dynamics. This can be quantified by the branching ratio of trajectories that visit one or other well to total number a system with potential two sequential index-1 saddles and wells (top bottom well). In our case, relative 1:1 because symmetry energy surface. The mechanisms transport behavior this kind systems have been studied recently. paper we study time evolution after selectivity as varies using periodic orbit dividing surfaces. We investigate what happens first trajectory region top for different values energy. answer natural question: What destiny these trajectories?
