摘要：
The polarized infrared reflection spectra of Li2B4O7 were studied in the spectral range 80-1600 cm(-1) and compared with Raman spectra. From the spectrum dispersion analysis, the frequencies, damping, and dielectric oscillator strengths were determined for all vibrational modes observed. A calculation of the effective charges and an analysis of the chemical-bond types of the Li2B4O7 crystal structural units were carried out on the basis of the obtained data.
