Zeolite spin-orbit splitting

It can also be useful to study variations in the spin-orbit splitting (AEs ), which occur with the first-row transition elements due to multiplet splitting effects. In an early investigation, Wichterlova et al. [117] noted a low AEs value for Cr in zeolite Y (9.1-9.2 eV vs. 9.8 eV in 203). Such low values were also foimd for low-percentage Cr(III) on SiOj and AI2O3 [117,118]. Thus, although reflecting the isolation of the MI rather than the specific zeolite environment, anomalous AEs ...
