Abstrakt: 1.Study of the IR spectra of unannealed corundum crystals grown in a hydrogen-oxygen flame established that all such crystals have absorption bands corresponding to OH-group valence vibrations and hence do not differ in this respect from other crystals grown under analogous conditions.2.The experimental data obtained in this investigation indicate that there is a relationship between the absorption bands corresponding to OH groups and the content of impurities requiring charge compensation in the crystals.
