To the origin of vibrational models in Raman spectra of Li₂B₄O₇ single crystals
The Raman spectra investigations have been reported at room temperature in the 100-1200 cm⁻¹ range for Li₂B₄O₇ single crystals with natural Li and B isotopic distribution and for 4 types of single crystals enriched maximally in ⁷Li, ⁶Li, ¹⁰B and ¹¹B isotopes. It has been found that in spectra of Li₂...
