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.
