In a spin: Directly differentiating multiple Mg sites in Mg-containing MOFs by (25)Mg solid-state NMR spectroscopy is very challenging at natural abundance. By performing (25)Mg two-dimensional triple-quantum magic-angle spinning solid-state NMR experiments at a magnetic field of 21.1 T at natural abundance, four non-equivalent Mg sites with very similar local environments in α-Mg(3)(HCOO)(6) were unambiguously resolved (see figure).
在旋转中
在自然丰度下，通过（25）Mg 固态 NMR 光谱直接区分含镁 MOF 中的多个 Mg 位点极具挑战性。通过在磁场为 21.1 T 的自然丰度下进行（25）Mg 二维三量子魔角旋转固态 NMR 实验，在α-Mg(3)(HCOO)(6)中四个局部环境非常相似的非等价 Mg 位点得到了明确分辨（见图）。
