The frequencies of the wurtzite‐like modes due to Li–O and Ga–O bond vibrations in LiGaO 2 and of the rocksalt‐like mode due to Li–O bond vibrations in LiInO 2 are determined from the infrared reflectivity spectra of the compounds. The force constants for the Li–O and Ga–O bonds in LiGaO 2 follow the same trends as those found for the A I B III C 2 VI chalcogenides with tetrahedral cordination. The results for LiInO 2 are compared with measurements on the octahedrally coordinated modification of LiAlO 2 .
