Abstract

Group Analysis of the infrared spectra of KClO4-KMnO4, KClO4-KBF4 and K2SO4-K2XO4 (where X is Se, Cr, Mn) mixed crystals was carried out. These systems form D2h16 orthorhombic substitution mixed crystals; the symmetry of the anion is Td. Analysis of the infrared spectra samples with sufficiently diluted studied anion revealed the expected decrease in symmetry to Cs symmetry.
