Conical intersection: Characters, Local characterization & Overview

In quantum chemistry, a conical intersection of two or more potential energy surfaces is the set of molecular geometry points where the potential energy surfaces are degenerate (intersect) and the non-adiabatic couplings between these states are non-vanishing. In the vicinity of conical intersections, the Born–Oppenheimer approximation breaks down and…

How Conical intersection connects Entity context

The extracted context around Conical intersection shows recurring relationship patterns in the source. For example, Conical intersection → C3h, C3v, Conical, Coulomb Hamiltonian, D3h, Jahn, Symmetry-required, Teller Another extracted example is Conical intersection → intersection between two electronic states carrying the same multidimensional irreducible representation, intersection between two electronic states that carry different point group symmetry, intersection between two electronic states that carry the same point group symmetry. Use these groups to spot repeated connection types before inspecting the individual relationships.
