利用Li+离子附着质谱法对C2H2/N2微波放电产物进行分析，意外地检测到C3N4。质谱在m/z为99处出现Li+加合物峰，初步确定为C3N4。探讨了生产C3N4的可能性。为了提高生产速率和确认该化合物在气相中的存在，改变了放电条件。产率随氮浓度的增加而增加。并进行了从头计算和密度泛函理论计算。
C3N4 species were unexpectedly detected in an analysis of the products in a C2H2/N2 microwave discharge using Li+ ion-attachment mass spectrometry. The mass spectra exhibited a Li+ adduct peak at a m/z of 99, which was tentatively assigned to C3N4. The possibility of the production of C3N4 was investigated. Discharge conditions were varied with a view toward increasing the production rate and confirming the presence of this compound in the gas phase. The production rate was found to increase with the nitrogen concentration. Both ab initio and density functional theory calculations were also performed.
