【摘要】 利用高压拉曼方法研究了高氯酸锂三水合物分子在高压极端条件下的分子结构变化。在室温下测量了从常压到29.61 GPa压力下高氯酸锂三水合物的高压拉曼光谱。通过对压力频移曲线分析,结果表明:在～4.45和～12.02 GPa发生了两次结构相变。高氯酸锂三水合物基于高压拉曼光谱的研究将帮助我们观察分子在极端条件下的行为,进一步理解分子的结构,对于高压下的化学合成研究有着重要的理论支持作用。更多还原

【Abstract】 In this paper,the high-pressure Raman method is used to explore the behavior of lithium perchlorate trihydrate molecules under high-pressure extreme conditions.We measured the high-pressure Raman spectrum of lithium perchlorate trihydrate at a pressure of up to 29.61 GPa using DACs at room temperature.Our data indicate that two structural phase transitions occurred near～4.45 and ～12.02 GPa.The study of lithium perchlorate trihydrate based on high-pressure Raman spectroscopy will help us observe the behavior of molecules under extreme conditions,further understand the structure of the molecules,and have important theoretical support for the study of chemical synthesis under high pressure.更多还原
