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.
