Magnetic coupling exhibits the spin delocalization effect from Mn and Cu atoms to the bridging atoms, and doesn't reveal metallically magnetic properties. 磁性耦合来源于铜和锰原子向桥联原子的自旋退局域化效应,且具有磁性特征但不具有金属性特征。
H-Abstraction from p-Substituted Benzaldehydes by Bis-perfluoroalkyl Nitroxides ── A New Attempt for Establishing Substituent Constants of Spin Delocalization σ by EPR Method 双-全氟烷基氮氧自由基从取代苯甲醛的攫氢反应&用EPR方法建立取代基自旋离域参数σ的新尝试
The Mulliken population analyses show that in the title complexes there is a spin delocalization mechanism of magnetic coupling through the bridges. Mulliken自旋布居分析表明,无论是三唑桥还是异硫氰酸根桥,它们的磁交换作用机理都是磁中心的自旋离域。
The analysis of the spin density distribution reveals that both the spin polarization and spin delocalization contribute to the antiferromagnetic interaction. 自旋密度分布表明,两相中自旋极化效应和自旋离域效应相互作用的结果导致体系表现为反铁磁相互作用。
