| 摘 要： | 对BiB3O6晶体(BIBO)的拉曼光谱进行了研究。BIBO的振动模分为外模和内模，外模总数是2A 5B，内模数是11A 10B。运用分子位置群分析的方法分析内模，BIBO的内模归属于[BO3]三角形和[BO4]四面体的振动模，[Bo2]和[Bo4]共享O原子。外部振动起源于Bi^3 、[Bo3]基团的平移模与[Bo3]基团的天平动。

| Abstract: | Raman spectra of BiB_3O_6 crystal(BIBO) was studied.It is an approximate treatment to divide the vibrational modes of the BIBO crystal into internal and external modes,the total number of external motions of BIBO are 2A+5B,the internal motions of the BIBO are 11A+10B.By using the method of molecular site group analysis,we attributed tentatively the internal modes BIBO to the vibrational modes of the BO_3 triangle and BO_4 tetrahedron,the BO_4 tetrahedron and BO_3 triangle share oxygen atoms.The external vibrations originated from the translational motions of Bi~(3+) and triborate anion group plus the librational motion of triborate anion group. |
