Abstract

Raman spectra of LiB₃O₅ and Li₂B₄O₇ crystals have been studied. Raman scattering efficiency and oscillator strengths of some polar vibrations were estimated. Contribution of various vibrations to nonlinear optical coefficients according their assignment has been discussed. Influence of K⁺ and Ag⁺ impurity ion on Raman spectra of Li₂B₄O₇ have been studied. Anomalies of the isofrequency temperature dependencies of Raman spectral intensity observed at T equals 235 K are interpreted in terms of the translation structural phase transitions.
