Spectral Properties of Alpha-Cu2(OH/D)3Br at Room Temperature

Article Preview

Abstract:

The newly identified magnetic geometric frustration material-botallackite-structure deuteroxyl copper bromide α-Cu2(OD)3Br sample was successfully synthesized in the same single phase (polycrystalline) as the H-isotope substituted sample of α-Cu2(OH)3Br, and its IR (4000-400 cm–1) absorption and Raman (4000-95 cm–1) spectra at room temperature are first, to the best of our knowledge, measured to study the corresponding relationship between these iso-structural compounds. Through the comparative analysis with those of α-Cu2(OH)3Br reported previously, we definitely assign or tentatively suggest their vibration modes according to the result of the factor group analysis.
