| 摘 要： | 碳原子簇的结构多年来吸引着理论与实验化学家的兴趣。我们以脉冲激光作用于石墨和主要为石墨微晶的无定形碳(木炭,焦炭等),对所产生的碳原子簇离子的质谱加以分析,发现当碳原子数n=13时,碳原子簇的结构从链状向环状转化,为了进一步确定碳原子簇的结构规律,又选取了晶体构型不同的玻璃态碳为样品,以相同的方法研究。

| Abstract: | Study of carbon clusters is one of the current lnterests in chemical research. With pulsed laser focused on a glassy carbon sample, the mass spectra of both positive and negative carbon cluster ions were observed. Analysis of the mass spectra shows structral configuraticn conversion from chain to ring with cluster size of 13, which is similar to the carbon clusters generated from graphite and other carbon samples. Those experimental results indicate that the structral configuration of corbon cluster depends on its size instead of the structure of bulk sample. |
