When the orbital functions are chosen as d-like or/-like, the axial symmetry of the molecule again leads to factorize the Renner-Teller Hamiltonian in a double chain. In effect the total angular momentum Jz remains a constant of motion and can be put in a diagonal form by means of the same type of canonical transformation, so we have...
