MS calculations of the O K-edge ELNES in titanite taking O2 as the center of the cluster. (a) 8-O-atom only cluster calculation; (b) the decomposed calculation of the two-shell cluster, suppressing the sp bases of Si; (c) the same as (b) but only suppressing the Si p bases; (d) the same as (b) but only suppressing the Si s bases; (e) the normal two-shell cluster results. |
