摘要
本文综合我们从NH_3F(氟化胺)、HCCl_3(氯仿)、HCBr_3(溴仿)、S_3(硫)和CNH(三聚氰胺)等分子晶体获得的高压Raman光谱数据,讨论了分子晶体 Raman光谱的谱带强度,频率位移,晶场劈裂和Gruneisen常数等对压力的依赖关系。总结了分子晶体压致结构相变的光谱证据和高压新相结构确定的几种方法。
Pressure dependence on the intensities and frequences of Raman bonds, crystal field splitting and mode-Gruneisen paramenter were discussed. Raman data were taken from our experements on NH3F, HCCl3,HCBr3,Sg and C3N6H6 et al. Raman spectroscopic evidence for pressure induced structure phase transition of molecule crystal and the methods to determine new phase under high pressure were sumed up.
