摘　　要：测定了三硼酸锂(LiB_3O_5)晶体和低温相偏硼酸钡(β-BaB_2O_4)晶体的红外吸收光谱,用量子化学方法对这两种晶体的化学键性质进行了研究。从而定性地解释了LiB_3O_5晶体复杂的红外吸收光谱特征,并给以初步指认。The Fourier transform infrared absorption spectra of the crystalline lithium triborate(LiB3O5)and barium metaborate(β-BaB2O4)in low temperature phase have been measured.For these two species of the crystalline borate the chemical bonding properties are studied by means of the quantum-chemical method.Whereby the qualitative exposition is given for the complicated infrared absorption spectra of the crystalline LiB3O5.The assignments of these spectra are discussed in detail as well.
