硼酸晶体结构分析及拉曼光谱测试

Boric Acid Crystal Structure Analysis and Raman Spectra Test

对硼酸（H3BO3/B（OH）3）粉末进行XRD测试,确定其空间结构和所属对称点群;对硼酸晶体进行晶格振动模式分析,确定其有18个拉曼活性模式4Ag＋2E1g＋5E2g;并对其进行50～3800cm-1波段的Raman散射测试,利用理论结果对谱图进行了讨论,确定了各振动峰的特性。

The crystal structure and the Group Space of Boric acid（H3BO3/B（OH）3） crystal has been determined from X-Ray Diffraction;And we have analyzed the lattice vibration of boric acid crystal,the Raman active vibration modes are 4Ag＋2E1g＋5E2g;Room temperature Raman spectra of the powder has been studied between 50 and 3800cm-1.The experiment results are discussed,and the characteristic vibrational peaks were identified.
