Figure 5
Refined structures of ZSM-5 crystal 1 from (a) unfiltered and (b) filtered data sets, showing ADPs for the Si and O atoms at the 60% probability level along the b axis. Red – oxygen atoms; blue – silicon atoms. The structure from the unfiltered data set contained many unreasonable ADPs; some became negative while the ADPs of the structure from the filtered data set were reasonable and closer to isotropic. |
