The HSQC (Heteronuclear Single Quantum Coherence) experiment is used to determine proton-carbon single bond correlations, where the protons lie along the observed F2 (X) axis and the …

HMBC (1H detected heteronuclear multiple bond correlation):为1H的异核多碳相关谱，将1H核和 远程 耦合的13C核关联起来，通常2~3个键的质子与碳的耦合信息较多。 释义. 长程异核位移 …

In an HMQC spectrum, a 13 C spectrum is displayed on one axis and a 1 H spectrum is displayed on the other axis. Cross-peaks show which proton is attached to which carbon. COSY spectra …

1：1h-nmr谱 核磁氢谱提供了化合物分子中有无活泼氢，各种活泼氢的分配及相互位置关系等。 该谱图表明,对氨基苯甲酸乙酷分子中有五种不等性的氢(没有考虑芳环上氢的区别)。

hmbc. 一维氢谱和碳谱描述了单个原子信息，2d nmr中的1h-1h cosy和hsqc，组合了相近原子间的信息，通过以上方式，我们仅知道分子的片段信息，只有再把片段与片段信息组合起来，我们 …
