Direct contact versus solvent-shared ion pairs in Ni[Cl.sub.2] electrolytes monitored by multiplet effects at Ni(II) L edge X-ray absorption
Article Abstract:
Ni L edge X-ray absorption spectroscopy is used to investigate the local electronic structure in aqueous Ni[Cl.sub.2] electrolytes. The electronic structure in the electrolyte has reflected the absence of direct contact Ni-Cl ion pairs and these changes are due to progressive distortions of the local symmetry induced by solvent-shared ion pairs.

Thermal decomposition of crystalline Ni(super II)-Cr(super III) layered double hydroxide: A structural study of the segregation process
Article Abstract:
A structural study of the thermal evolution of Ni0.69Cr0.31(OH)2(CO3)0.155n.H2O into NiO and tetragonal NiCr2O4 is reported. The result reveals that the nucleation of a metastable nickel chromite within the common oxygen framework of the parent Cr(super III)-doped bunsenite is the initial step of the cationic redistribution.

Local coordination of low-spin Ni (super 3+) probes in trigonal LiAl(sub y)Co(sub 1-y)O2 monitored by HF-EPR
Article Abstract:
A study was conducted on the local coordination of low-spin Ni (super 3+) probes in trigonal LiAl(sub y)Co(sub 1-y)O2 using high-frequency EPR spectroscopy. The maximum effect of Jahn-Teller distortion is achieved when the Ni (super 3+) ion falls in a pure Al environment.
