Abstract:

Infra-red absorption spectra of selected families of inorganic solid compounds have been registered and discussed. The following types of compounds have been investigated 1 Compounds with, or related to, the MgO NaCl structure. The spectrum, which is very simple for compounds with the true NaCl structure, is more complicated for LiXIIIO2 compounds in this latter type of compounds, the study of 6Li - 7Li isotopic shifts shows that the low-frequency band in the 300 - 200cm region must be assigned to a vibration of LiO6 octahedra, whereas the 600 - 400cm absorption is essentially related to vibrations of the XIIIO6 octahedra. 2 Lithium compounds of various types. In this case, a systematic investigation of 6Li - 7Li isotopic frequency shifts demonstrates the occurrence of various weak to very strong types of vibrational interactions. 3 Compounds with the BaSO4 structure. Three problems have been investigated the occurrence of frequency shifts in the spectrum of BaSO4 in relation with the methods of synthesis the IR pattern of compounds of this type for different cations and anions the IR spectrum of solid solutions.
