摘要 以并六苯环石墨烯带为研究对象,采用密度泛函理论的B3LYP方法,及6-31+G(d)基组,对该模型进行了分子轨道分析和频率计算。通过轨道分析得出了分子轨道能隙和轨道密度;经过频率计算得出模型的红外和拉曼光谱并说明了振动光谱中出现强峰的原因;最后与加氢并六苯环比较,对并六苯环石墨烯带的稳定性进行了讨论。 The orbital energy and the frequency of the six-benzene-ring graphene without H atom have been studied by using B3LYP method and 6 -31 + G(d) basic set. The molecular orbital density and energy gap have been obtained through orbital analysis, the infrared and Raman spectrum has also been obtained, and the reason why peaks appear was explained. Finally, compared with 6 benzene rings graphene with H atoms, and the stability of the sixbenzene-ring graphene has been discussed.
