摘要
利用群论分析方法对Bi_2Sr_2CaCu_2O_(?)正交晶系简正模进行了详细分析,预测了该超导体系的红外吸收峰和拉曼吸收峰的数目,为在实验上晶格振动光谱分析提供了理论依据.
In this paper, normal modes of orthogonal crystal system in Bi2 Sr2CaCu2Ox compound, are analysed in detail by means of theory of group amalysis. The number of IR peaks and Raman peaks in Bi2Sr2CaCu2Ox compound system is predicted, It supplies a powerful theory for lattice vibration experiments.
