Tunable single‐molecule magnets: The spin‐level landscape in a series of FeIII4 single‐molecule magnets with propeller‐like structure was analyzed by means of high‐frequency EPR spectroscopy. The zero‐field splitting parameter D of the ground S=5 spin state correlates strongly with the pitch of the propeller γ (see picture), and thus provides a simple link between molecular structure and magnetic behavior
可调谐单分子磁体:通过高频EPR光谱分析了一系列具有螺旋桨状结构的Fe III 4单分子磁体中的自旋能级分布。基体S = 5自旋态的零场分裂参数D与螺旋桨γ的螺距密切相关(参见图片),从而在分子结构与磁行为之间建立了简单的联系。
