Laser-ablated aluminum atoms react with dinitrogen on condensation at 10 K to form N3 radical and the subject molecules, which are identified by nitrogen isotopic substitution, further reactions on annealing, and comparison with isotopic frequencies computed by density functional theory. The major AlN3 product is identified from three fundamentals and a statistically mixed nitrogen isotopic octet pattern
激光烧蚀的铝原子在 10 K 时与二氮发生缩合反应,形成 N3 自由基和目标分子,通过氮同位素取代、退火的进一步反应以及与密度泛函理论计算的同位素频率比较来识别。主要的 AlN3 产品是从三个基本面和统计上混合的氮同位素八位组模式中确定的。富含铝的 Al2N 和 Al3N 物质是退火时的主要产物,以允许被捕获物质的扩散和进一步反应。这项工作为可能参与陶瓷膜生长的分子 AlxNy 物种提供了第一个实验证据。
