摘要: 用INDO法研究了C62O3的结构与光谱。结果表明,C62O3有C2v和Cs两种稳定构型,其中G2v构型能量较低。利用C60的碎片拓扑图讨论其加成及环加成产物对称性的规律,理论计算与13C NMR谱的实验结果相符合。进一步从能量及稳定性的角度比较C60的三元环及五元环衍生物。同时,对电子跃迁进行了理论指认,并讨论了C62O3谱带红移的原因。

Abstract: INDO calculation was used to study the two structures of C62O3:one of C2v symmetry and the other of Cs symmetry.A patch of topology of C60 was employed to discuss the symmetry of additive and cycloadditive products of C60 and related to 13C NMRresults.Stability comparison was made between the devivatives of three-membered and five-membered rings.The calculated electronic spectrum for C62O3 C2v)is in agreement with the experimental results.
