The O-ccntcr in CaFa is invcstisatcd by performing multiple scattcrirq Xa calculations on the (Ore)'-cluster. In agreement with cxpcrimcnt, a strong Jahn-Teller distortion of tctrqondl symmetry is prcdictcd. Finally the ground state electronic structure of the cluster is discussed.
Structural changes accompanying the electrochemical Li deintercalation of Li 1؊x NiO 2 and Li 1؊x CoO 2 were studied by the transmission X-ray absorption fine structure (XAFS) technique using an in situ X-ray cell of original design. Our results revealed that the Jahn-Teller distortion of the Ni-O o
