Conical Intersection
A conical intersection of two potential energy surfaces is the set of molecular geometry points where the two potential energy surfaces (PESs) intersect; when they are degenerate. A condition is that both PESs are of the same spatial and spin symmetry.
If two PESs are plotted as functions of 2 coordinate, they form a cone centered at the degeneracy point. Hence the name conical intersection.
Synonyms for conical intersection:
molecular funnel
diabolic point
Other related terms:
Seam = the intersection space = geometry points that are degenerate ; have equal energy
Branching space = the dimensions that lift the energy degeneracy of the system
