Bimessite, local structures

The sensitivity of EXAFS to changes in the local structure of MnOa polymorphs is illustrated in Figure 7, where the RDF of bimessite (a phylloman-ganate) and todorokite (a tectomanganate) are compared. The RDF of phyl-... [Pg.124]

Figure 8. Local structures of bimessite and todorokite. The linkage of octahedra along edges and double comers is abbreviated by E and DC, respectively. Distances are from Rietveld refinements of powder diffraction data (31, 36). They can be compared with the average distances obtained from EXAFS in Table III.
