Homonuclear correlations are key to structural studies using solid-state NMR. In this contribution, using 14N overtone transition (OT) as a selective excitation approach, we propose a proton-detected one-dimensional (1D) 14NOT/14NOT/1H correlation solid-state NMR method mediated through 1H/1H mixing at fast magic angle spinning to achieve NH/NH proximities in naturally abundant samples. The proposed method is time efficient by a factor of ∼7.5 in comparison to the existing fundamental 14N frequency-based three-dimensional (3D) 14N/14N/1H correlation method.

在快速MAS下通过1 H / 1 H混合 进行14 NH / 14 NH泛音相关的一维固态NMR方法

同核相关性是使用固态NMR进行结构研究的关键。在此贡献中,我们使用14 N泛音跃迁(OT)作为选择性激发方法,我们提出了一种质子检测的一维(1D)14 N OT / 14 N OT / 1 H相关的通过1 H介导的固态NMR方法/ 1 H在快速魔角旋转中混合,以在自然丰富的样品中达到NH / NH邻近度。与现有的基于基本14 N频率的三维(3D)14 N / 14 N / 1相比,该方法的时间效率高7.5倍。H相关法。
