Crystal field spectra of Ni2 olivines

A detailed investigation of the polarized spectra of a wide compositional 

5 Crystal field spectra of transition metal ions 

Crystal field parameters derived from the polarized absorption spectra of Mg-Ni olivines were expressed by the empirical equations (Hu et ah, 1990) 

The value of A, and hence the calculated CFSE, for Ni2+ ions in the olivine Ml sites appears to be anomalously high compared to values acquired in other octahedral sites in oxide structures, including bunsenite and MgO (table 5.1), Ni2Si04 spinel ( 5.4.3), and other phases listed later (table 5.19). The dis-crepency results from incorrect assignments of bands i and j listed in table 5.4
