aromaticity

It was theoretically predicted that polyvalent anions of C 36 CH 2 had high stability and aromaticity.

从理论上预计C36CH2的高价阴离子具有很高的芳香性和稳定性.

Six major criteria of aromaticity, namely Dewar resonance energy, Huckel rule and Hess's REPE index, PMO criterion, extended Huckel, rule and physical method, were introduced. The limitations and advantages of them were discussed in this paper.

分析6种判断化合物是否具有芳香性的规则即Dewar共振能、休克尔规则、汉斯的REPE指标、PMO判据、推广的休克尔规则及物理方法，并对各种判据的局限性和优点作了比较。

It is shown that the aromaticity order of these molecules evaluated on basis of the pseudo-delocalization energies is essentially in accordance with those reported in the references, which shows the reasonableness and usableness of the aromaticity criterion proposed in this paper.

根据准离域能标准判断的分子芳香性大小顺序与文献的结果基本一致，表明本文提出的芳香性量度标准的有效性和可用性。
