C^+60的激光产生与质谱研究 总被引:4,自引:0,他引:4
1985年10月美国Rice大学Smalley的研究小组报道了含有60个碳原子的原子簇的质谱检测结果,根据对质谱的分析,认为它具有超稳定的足球形笼状结构。但这一结构尚未得到分子光谱等数据的直接证实。 相似文献

C90-150+的质谱与结构分析 总被引:2,自引:2,他引:2
It was proposed that all carbon clusters with n>30 have geometrically closed cage structures. The mass spectrum of C_(92-151)~+ was observed on a self-built laser probe time-of-flight mass spectrometer. The spectrum showed that for cluster size less or equal to 126, only even-number cluster exists, which is consistant with a closed structure. The system was broken for cluster larger than 126. This observation indicates that the structural configuration changes with increase of the cluster size. 相似文献
