MO Theory for Polyatomic Molecules - Delocalization

MO Theory for Polyatomic Molecules - Delocalization. MOs in polyatomic molecules can be localized between two atoms, or dispersed over multiple atoms (delocalized) Sigma bonds are often localized Pi bonds may be delocalized, as in the case of conjugated molecules
