今天的化学研究如果没有核磁共振是很难设想的。核磁共振对于探查溶液中的分子结构,研究固体材料以及分子动态已证明具有极丰富的信息来源。为了应付如此大量的信息,向二维谱扩展就成为很自然了。自从十二年前开始以来,二维谱已对下列几方面作出了贡献:用二维相关谱为解释偶合网络提供了许多有力的技术;用二维交叉弛豫谱测量核间距离;用二维交换谱研究化学交换网络。这些新的技术在化学及生物学中大分子的分析时往往难以理解。
Today’s chemical research is difficult to imagine without NMR. Nuclear magnetic resonance has proven to be a very rich source of information for exploring molecular structures in solution, studying solid materials and molecular dynamics. In order to cope with such a large amount of information, it becomes natural to extend the two-dimensional spectrum. Since the beginning of twelve years ago, two-dimensional spectra have contributed to the following aspects: the use of two-dimensional correlation spectroscopy to explain the coupling network provides many powerful techniques; two-dimensional cross relaxation spectrum to measure the distance between the nuclei; Dimensional exchange spectrum research chemical exchange network These new techniques are often difficult to understand in the analysis of macromolecules in chemistry and biology.
