摘要: 在压力为0~8.7GPa内测量了三聚氯胺C3N6H6的高压Raman光谱,讨论了其谱带强度、频率和模Grüneisen参数等的压致效应,结果表明三聚氯胺在大约2GPa和6GPa发生两次结构转变,第一次可能由P21/α(C25h)空间群转变为I(Ci)空间对称性。

Abstract: High-Pressure Raman spectra for C3N6H6(Melamine) were measured at the range of 0~8. 7 GPa. The pressure effect of the intensity, frequency and mode-Gruneisen parameter(vi) were discussed. The Experemental results show that melamine probably undergoes two structural transitions at 2 GPa( Ⅱ ) and 6 GPa( Ⅲ ) respectively and phase Iis of Ci ymmetry probably.

Key words: Melamine, Raman spectra, Pressure effect, Structure phase transition
