摘要：

The frequencies of the wurtzite‐like modes due to Li–O and Ga–O bond vibrations in LiGaO2 and of the rocksalt‐like mode due to Li–O bond vibrations in LiInO2 are determined from the infrared reflectivity spectra of the compounds. The force constants for the Li–O and Ga–O bonds in LiGaO2 follow the same trends as those found for the AIBIIIC2VI chalcogenides with tetrahedral cordination. The results for LiInO2 are compared with measurements on the octahedrally coordinated modification of LiAlO2. Copyright © 1990 WILEY‐VCH Verlag GmbH & Co. KGaA
