我们报告了两种最近发现的硝基硝基氧，1-和2-萘基硝基氧（1-NAPNN 和 2-NAPNN）的μ子自旋旋转/弛豫（）实验结果。这两种化合物是化学异构体，但由于它们的分子形状略有不同，因此它们的晶体堆积有很大不同。在低于 100 mK 的 1-NAPNN 中观察到零场 μ 子自旋弛豫中的明显磁转变，而在 2-NAPNN 中没有看到这种转变。这些结果支持这样的假设：晶体结构强烈影响这些材料中磁性基态的性质。
We report the results of muon-spin-rotation/relaxation () experiments on two recently discovered nitronyl nitroxides, 1- and 2-naphthyl nitronyl nitroxide (1-NAPNN and 2-NAPNN). These two compounds are chemical isomers but, because of their slightly different molecular shapes, they have quite different crystal packing. A clear magnetic transition in the zero-field muon-spin relaxation is observed in 1-NAPNN below 100 mK while no such transition is seen in 2-NAPNN. These results support the postulate that the crystal structure strongly influences the nature of the magnetic ground states in these materials.
