The character of non-bonding molecular orbitals (and the related spin-density) is addressed in the general circumstance of translationally symmetric graphenic strips. Besides a systematic characterization of such possible strips, couplings are addressed between boundary-localized unpaired spins, including the case when opposite sides of a strip are two different types of (translationally symmetric) boundaries.

平移对称石墨烯条

非键合分子轨道（以及相关的自旋密度）的特征在平移对称石墨烯带的一般情况下得到解决。除了对此类可能的条带进行系统表征外，还解决了边界局部化不成对自旋之间的耦合问题，包括条带的相对侧是两种不同类型的（平移对称）边界的情况。
