 Title: THE NEAR INFRARED ABSORPTION SPECTRA OF LiOH, LiOD AND MIXED CRYSTALS OF LiOH AND LiOD NEAR $4^{\circ} K$ Creators: Buchanan, R. A.; Caspers, H. H. Issue Date: 1960 Abstract: “Low temperature near infrared absorption spectra of single crystals of LiOH and LiOD as well as spectra of mixed crystals of varying concentrations of LiOH in LiOD are presented. The temperature dependence, unusual band shapes and deuteration effects are discussed. Changes in the spectrum of LiOH when diluted in LiOD as well as changes in the spectrum of LiOD when diluted in LiOH are described. These experimental observations are seen to be in better agreement with the model which assumes that lattice vibrations are coupling to the internal hydroxyl stretching $frequency^{1}$ than with the model which assumes localized librations or rotations of the hydroxyl $ion^{2,3}$.” URI: http://hdl.handle.net/1811/7978 Other Identifiers: 1960-J-6
