Nitrogen-14 (spin I=1) has always been a nucleus difficult to observe in solid-state NMR and until recently its observation was restricted to one-dimensional (1D) spectra. We present here the first 3D 1H-13C-14N NMR correlation spectrum. This spectrum was acquired on a test sample L-histidine.HCl.H2O using a recently developed technique, which consists in indirectly observing 14N nuclei via dipolar recoupling with an HMQC-type experiment.
氮-14（自旋I = 1）一直是固态核磁共振中难以观测的原子核，直到最近其观测还仅限于一维（1D）谱。我们在此展示了首个三维1H-13C-14N核磁共振相关谱。该谱是使用一种最近开发的技术在测试样品L-组氨酸·盐酸盐·水合物上采集的，该技术通过与HMQC型实验的偶极重耦合间接观测14N原子核。
