According to the Jahn Teller effect:

שאלה #26923

If the HOMO and LUMO of one molecule have the same symmetry, they can interact.

If the highest occupied orbitals are degenerate and singly occupied, the geometry will distort.

If the gap between occupied and unoccupied orbitals is small, the molecule will prefer a higher multiplicity.
