Long-range orbital order

The second inaccuracy is a mix-up between cause and effect. Obviously, the two phenomena, crystal lattice distortion and low-symmetry orbital ordering, are interrelated. However, the JT distortion can take place even without any long-range orbital ordering. Above the temperature of structural (JT) phase transition, in each elementary cell, the JT effect is still active. Considered separately from one another, due to the JT effect, elementary cells can be locally distorted. These local distortions are not ordered, and respective X-ray data provide evidence of time averaged high symmetry lattice. However, above the temperature of structural phase transition, disordered JT distortions manifest themselves in XAFS [58]. 

S 3p orbital to the HOMO of DMET or EDTDM molecule. Therefore It J and also I JndI of the EDS-TTF salt becomes negligibly small compared to the DMET or EDTDM salt. It should also be noted that the intermolecular Br—Br distance between FeBr4 anions is almost the same among the EDS-TTF, DMET and EDTDM salts. Therefore this also proves the importance of the n-d interaction in the long-range magnetic ordering of the -electron spins.
