采用密度泛函理论(DFT),在B3LYP/6-31G*水平上,对金刚烃分子(C4n+6H4n+12,n=1~4)的全部七种分子结构进行构型优化,筛选出最低能量构型.并在此基础上,对其拉曼光谱进行计算,根据振动模式对其特征峰进行了指认.

关键词: 金刚烃, 密度泛函理论, 分子结构, 拉曼光谱

Using B3LYP/6-31G* method of DFT to optimize and investigate the energy of all the seven structures of diamondoids (C4n+6H4n+12, n=1~4), and the lowest energy structure was got. At the same level, their Raman spectra were investigated, and the harmonic vibratory mode of the peaks was indicated subsequently.

Key words: diamondoid, DFT, molecular structure, Raman spectra
