Abstract

Using a YB66 monochromator X-ray absorption measurements were carried out at the Al K and Si K absorption edges of a series of aluminosilicate sodalites. The AlOSi bridging angle of the selected sodalites varies from 138° to 148° and the structure of the XANES with its different multiple scattering (MS) features shows a strong angular dependence. Increasing the angle results in a decrease of the MS intensities. This dependence is especially pronounced at the Al K edges which contain a couple of separated well-resolved peaks whereas the corresponding features at the Si K edges are smeared out due to a strong overlapping of the peaks.
