求助关于NOESY谱中，产生NOE效应的两氢核的空间距离小于5Å的文献？文章题目： Nuclear Magnetic Resonance (NMR) Spectroscopy: Structural Analysis of Proteins and Nucleic Acids 我摘录的： Nuclear Overhauser enhancement (NOE) The NOE effect results from dipolar cross-relaxation between two nuclei near each other in space. Since the phenomenon is dependent on the distance between nuclei, the NOE reports on the spatial separation of the nuclei whether or not the atoms, within which the nuclei reside, are chemically bonded to one another. For proteins and nucleic acids, the NOE can be measured for atoms that reside 5A˚ apart from one another. The NOE effect is extensively used to define the spatial arrangements of atoms in the three-dimensional structure of a protein or nucleic acid.查看更多
