薁，苯并环丁二烯和戊搭烯的拓扑共振能

Topological Resonance Energies of Azulene,Benzocyclobutadiene and Pentalene

为了阐明芳香性及磁性原因，用Ａｉｈａｒａ提出的ＴＲＥ概念计算了 ，苯并环丁二烯和戊搭烯等烃的共振能，环共振能和环电流．计算结果表明 因有正共振能具有芳香性并产生反磁性环电流，而苯并环丁二烯和戊塔烯因有负共振能具有反芳香性并产生顺磁性环电流．

In order to clarify the origin of the aromaticity and magnetic properties of hydrocarbons such as azulene,benzocyclobutadiene and pentalene,the resonance energies,circuit resonance energies and circuit currents were calculatd by means of Aihara's topological resonance energy(TRE).The calculation results indicated that azulene is predicted to be aromatic with positive resonance energy and give rise to diamagnetic ring current.while the benlocyclobutadiene and pentalene are predicted to be antiaromatic with negative resonance energies and give rise to paramagnetic ring currents.
