The infrared spectra were studied for the pyramidal ClO3- anion (C3v) embedded in host structures of various symmetries. Small amounts of NaClO3 or KClO3 were incorporated in NaBrO3 (T4), NaIO3 (D162h), KBrO3 (C3v5), and KIO3 (C11) structures. The ClO3- anion was found to assume the site symmetry of the host structure anion, i.e. C3, Cs, C3v, and C1, respectively, in accordance with the results of group analysis.
