轨道分子由轨道有序（有时也是电荷有序）固体（如过渡金属氧化物）中几个金属离子上的耦合轨道态组成。自旋单重态二聚体在许多材料中都是已知的，但最近发现的更奇特的物种，如18电子七聚体在AlV2O4和磁性3原子三聚体在磁铁矿（Fe3O4）表明，轨道分子构成了一个一般的新类别的量子电子态在固体中。(C)2015年作者。
Orbital molecules are made up of coupled orbital states on several metal ions within an orbitally ordered (and sometimes also charge-ordered) solid such as a transition metal oxide. Spin-singlet dimers are known in many materials, but recent discoveries of more exotic species such as 18-electron heptamers in AlV2O4 and magnetic 3-atom trimerons in magnetite (Fe3O4) have shown that orbital molecules constitute a general new class of quantum electronic states in solids.
