| Abstract: | The composition dependence of the d-spacing of Cs1?xRbx vermiculite has been determined for 0 ≤ × ≤ 1. It exhibits a step-like drop with increasing x at a composition that is unexpectedly lower than that at which Cs1?xRbxC8 shows a more gradual drop. This results attributed to in-plane substrate distortions which preserve the rigidity of the vermiculite layer. Measurements of the torsional Raman mode of Cs1?xRbx vermiculite support this analysis. |
