Molecular systems propellane structures

Fig. 3.11. Examples of the possible non-transversal intersections in a molecular system (a), between the stable and unstable manifolds of two bond critical points in CHJ (b) between the stable and unstable manifolds of two ring critical points in a distorted structure of [l.l.l]propellane (c) between ihe unstable manifold of a bond critical point with the stable manifold of a ring critical point (the ring axis) in face-protonated cyclopropane.
