摘要:
为了解四唑环在激光作用下的分解和簇合行为,在高真空条件下,以高纯氮气为载气,用纳秒激光分别溅射四唑、5-氨基四唑以及四唑与氮化锆、钒和铬形成的混合样品,并用反射式飞行时间质谱分析了生成的产物。结果表明,在532 nm的激光轰击条件下,大量四唑、5-氨基四唑分子骨架保持完整,易脱去一个氢原子而形成高丰度的负离子,该负离子进一步与1~3个四唑、5-氨基四唑分子形成簇合物;在氮化锆、钒和铬存在下,激光轰击四唑后形成了四唑正离子及四唑分子数不超过2个的簇合物,正离子质谱未发现锆、钒和铬参与四唑簇合物的形成。研究结果表明,激光溅射含氮有机物主要是蒸发作用,可用该方法表征有机物并研究其相互作用特性。
Abstract:
To understand the decomposition and cluster behavior of tetrazole ring under laser ablation, tetrazole, 5-aminotetrazole, the mixture of tetrazole and zirconium nitride, vanadium, chromium were ablated by nanosecond laser with N2 as carrier gas, and the products were analyzed by reflection time-of-flight mass spectrometer. The results show that the skeleton of tetrazole and 5-aminotetrazole basically remains intact under laser ablation, and they tend to convert to high-abundance anions by losing one hydrogen atom and these anions associate further with 1-3 tetrazoles and 5-aminotetrazole molecules to form corresponding clusters. In the presence of ZrN, V and Cr, tetrazole cation and clusters with no more than 2 tetrazoles are formed, and positive ion mass spectrum cannot find these transition metals participating in the formation of tetrazole clusters. It is found that evaporation is identified to occur in laser ablation of nitrogen-rich compounds, and laser ablation can be used to characterize nitrogen-rich compounds and study their interaction characteristics.
