三维NMR谱

３ＤＮＭＲ谱是２ＤＮＭＲ谱附加一个时间周期扩展而成，３ＤＮＭＲ共振峰的重叠降低，并且灵敏度与常规的２ＤＮＯＥＳＹ实验大体相当，采集３ＤＮＭＲ数据组所需时间太长，因此迄今为止，该方法的实际应用只局限于那些浓度相当高的样品。尽管目前还十分费时，但很可能３ＤＮＭＲ不久即可成为常规的ＮＭＲ技术。

3D NMR Spectroscopy

D NMR spectroscopy expends 2D NMR spectroscopy by appending an additional time period.3D NMR spectroscopy resonance overlap was reduced and the sensitivity is approximately comparable to a regular 2D NOESY experiment.The time to be taken for acquiring 3D NMR data set is so long that it has so far limited the practical utility of the technique to samples that can be examined at fairly high concentrations.Although very time-consuming at present.it is likely that 3D NMR will soon become a routine NMR technique.
