- 中文摘要: 利用拉曼光譜方法研究結晶四溴化鈦在不同溫度下的振動拉曼光譜,藉該晶體已知之分子及結晶結構,用群論方法對所得出之晶格振動與伸縮模式加以分析研究,顯示結晶四溴化鈦為一立方結構。
- 英文摘要: The vibrational spectra of polycrystalline titanium tetrabromide at various temperatures between80K and 300K have been investigated by Raman spectroscopic techniques. The observed modes are dis-cussed in terms of the known molecular and crystal structures. The simplicity of the lattice and strechingspectra indicates the cubic structure of crystalline TiBr.
