1.
It is proved that there are topological rules for the magnetic couplings between the radicals of nonplane conjugated systems: In conjugated system, the effective exchange integrals of radical sites through the even number of carbons with a π - electron network are negative i.
采用量子化学ab initio法对具有甲氧基的碳、氮双自由基邻、间、对二甲氧基亚甲基苯及衍生物体系基态自旋耦合规律进行研究,得到非平面共轭体系中自由基之间磁性耦合的拓朴规则:共轭体系中,两个自由基之间以偶数个碳原子耦合,则有效交换积分J_(ij)<0,体系具有低自旋基态;两个自由基之间以奇数个碳原子耦合,则J_(ij)>O,体系具有高自旅基态。
2.
The results show that the effective exchange integral values are less than zero under different conformations, so the radicals display the anti-ferromagnetic coupling.
结果表明,不同构象下各体系有效交换积分值都小于零,自由基间表现为反铁磁性耦合。
