摘要: 用abinitio分子轨道UnrestrictedHartree-Fock(UHF)方法,对N@C60的几何构型进行了全优化.计算结果表明,N基本上以原子的形式存在于笼中,但N原子与碳笼之间存在一定的相互作用,这与实验结果相符.进一步计算了N@C60的振动光谱,并与C60进行了比较分析.

关键词: N@C60, 电子结构, 振动光谱

Abstract: The geometry of N@C60 was optimized by using ab initio Unrestricted Hartree-Fock method. The results show that nitrogen is in the center of the cage in the form of atom basically, but there are some interactions between nitrogen atom and carbon cage. That is in agreement with the experimental results. We further calculated the vibrational spectrum of N@C60 and compared it with C60.

Key words: N@C60, Electronic structure, Vibrational spectrum
