## Abstract The composition dependence of the Raman spectra of the mixed ion vermiculites [(CH~3~)~4~N^+^]~1‐__x__~ [(CH~3~)~3~NH^+^]~__x__~‐V (V = vermiculite) have been studied in the range 0 ⩽ __x__ ⩽ 1. The torsional mode frequencies exhibit a small shift (__ca.__ 2 cm^−1^) to lower energy with
