描述了基于二维NMR粉末光谱确定分子相互作用张量相互取向的方法。必要的条件下，得出这一决定可以作出，程序的计算和分析的二维粉末光谱表示和技术的建设脊图制定。化学位移分辨偶极粉末光谱提供了一个容易解释的表示化学屏蔽和偶极耦合张量的相互取向。用苯、甲酸铅和甲酸甲酯的二维粉末光谱展示了这种光谱的各种特征和实际应用。
Methods are described for determining the mutual orientation of molecular interaction tensors based on two‐dimensional NMR powder spectra. Necessary conditions are derived under which this determination can be made, procedures for the computation and analysis of 2D powder spectra are indicated and a technique for the construction of ridge plots is worked out. Chemical shift resolved dipolar powder spectra provide an easily interpreted representation of the mutual orientation of chemical shielding and dipolar coupling tensors. The various features and practical applications of such spectra are demonstrated with 2D powder spectra of benzene, lead formate, and methyl formate.
