... of the bands around 550 cm −1 in the series milarite-almarudite-friedrichbeckeite, with a clear splitting with maxima of 577 and 543 cm −1 in friedrichbeckeite. This splitting, a reflection of short-range order, is thought to be the result of increased distortion of the T 2 tetrahedron in the series...
