Infrared spectra of LiOH and Li2CO3 suspended on KBr discs were measured over the concentration range 20 μg 100 mg KBr to 600 μg 100 mg KBr. The absorbance of a selected infrared band for each sample was carefully determined. The empirical equation, which expresses a correlation between the absorbance and the concentration, was given for each lithium compound. The feasibility of independent and direct determination of the LiOH and Li2CO3 content in Li2O was shown, and the spectroscopic technique was applied to a typical Li2O sample. It was shown that the detection limit of the analysis was improved by low-temperature measurements of the infrared spectra.
