Abstract
Infrared spectra of mixed-alkali diborate glasses, (Li, Na)20.2B2O3 and (Li, K)20.2B2O3, have been investigated. B---O stretching and B---O---B bending frequencies exhibit nonlinear shifts which can be described as a mild mixed-alkali effect. Both shifts and nonlinear variations of frequencies may be explained on the basis of alteration of the structure of the diborate groups in the presence of Li+ ions.
