Molecular Orbitals - Molecular Orbitals for Heteronuclear ... Molecular Orbitals for Heteronuclear Molecules. The molecular orbitals which describe the motion of a single electron in a molecule containing two unequal nuclear charges will not exhibit the g and u symmetry properties of the homonuclear diatomic case. The molecular orbitals in the heteronuclear case will in general be concentrated more around one nucleus than the other.
