The same analysis can be applied to the disrotatory mechanism to create the following state correlation diagram.
12.
The symmetry-imposed barrier heights of group transfer reactions can also be analyzed using correlation diagrams.
13.
This says that energetic configurations of the same symmetry can not cross on an energy level correlation diagram.
14.
One further relevant point is that the first organic correlation diagrams were in a 1961 publication on carbanion rearrangements.
15.
The graphs that are plotted to make this discussion clearer are called "'correlation diagrams " '.
16.
A molecular orbital correlation diagram correlates molecular orbitals of the starting materials and the product based upon conservation of symmetry.
17.
In the correlation diagram, molecular orbitals transformations over the course of the reaction must conserve the symmetry of the molecular orbitals.
18.
The figure to the right shows the molecular orbital correlation diagram for the [ ? 2 s + ? 2 s ] cycloaddition.
19.
However, as reactions do not take place between disjointed molecular orbitals, but electronic states, the final analysis involves state correlation diagrams.
20.
Correlating the pairs of orbitals in the starting materials and product of the same symmetry and increasing energy gives the correlation diagram to the right.
