IR and polarized Raman spectra of KIO₃ · Te(OH)₆

Abstract

The IR and polarized Raman spectra of the addition compound KIO, -Te(OH), were recorded and analysed.Bands indicate that the 10,-ion is distorted in this crystal and its symmetry is less than its free ion symmetry, C,, . The TeO, ion occupies a lower symmetry, C,, than its free ion symmetry, 0,.

“…The assignations of IR bands in some other metal iodates were also studied by others [24][25][26]. Santha and Nayar [24] recorded IR spectrum of KIO 3 ·Te(OH) 6 , and the authors assigned the IR bands at 370 and 395 cm −1 to v 2 vibration; 735 cm −1 to v 1 vibration; 750 and 799 cm −1 to v 3 vibration. The IR bands observed at 228 cm −1 and lower wave numbers were considered in terms of transitional and rotational modes in IO 3 − .…”

“…The band at 1033 cm À1 originates from the symmetric stretching (n s ) PO 3 vibrations with the A g symmetry species, whereas the P-O-P stretching modes of the Co 2 P 2 O 7 are represented by the bands in the 975-675 cm À1 range. 24 Notably, the Raman band at 948 cm À1 is due to the asymmetric bridge P-O-P stretching, whereas the symmetric P-O-P stretching mode is seen at 748 cm À1 . 25 Additionally, the band at 627 cm À1 could be related to the vibrational modes of water.…”
