He also noted that Mulliken had previously attempted to construct a correlation diagram for the possible orbitals of a polyatomic molecule in two different nuclear configurations, and had even tried to use this diagram to explain shapes and spectra of molecules in their ground and excited states.

Additionally, the correlation diagram for any 4n electrocyclic reaction will resemble the diagram for the 4 electron cyclization of 1, 3-butadiene, while the correlation diagram any 4n + 2 electron electrocyclic reaction will resemble the correlation diagram for the 6 electron cyclization of 1, 3, 5-hexatriene.

"' Walsh diagrams "', often called "'angular coordinate diagrams "'or "'correlation diagrams "', are representations of calculated orbital binding energies of a molecule versus a distortion coordinate ( bond angles ), used for making quick predictions about the geometries of small molecules.
