Definition and Qualitative Explanation

FIGURE 5.1 Schematic view of conical intersection of two adiabatic potential energy surfaces. 

FIGURE 5.2 Transmission probability vs. energy. The oscillatory curve (solid line) corresponds to the nonadiabatic tunneling with the nonadiabatic coupling with the excited state taken into account. The monotonous curve (dotted line) is the ordinary transmission probability with the coupling neglected. 

FIG U RE 5.3 One-dimensional model of the control of photodissociation with use of the complete reflection phenomenon. Solid line ground state Vi(r) dotted line excited state V2(r). Two circles represent the nonadiabatic mnnehng type curve crossings between the excited state and the dressed ground state. A vibrationally excited state that dissociates either to the right or to the left is depicted. (Taken from Reference [97] with permission.)
