Abstract
Dynamical systems theory is used to construct a general phase-space version of transition state theory. Special multidimensional separatrices are foun d which act as impenetrable barriers in phase-space between reacting and no nreacting trajectories. The elusive momentum-dependent transition state bet ween reactants and products is thereby characterized. A practical algorithm is presented and applied to a strongly coupled Hamiltonian.
