质子谱的宽带同核解耦，即所有多重态塌缩成单态，有可能提高 H-1 NMR 谱的分辨率。过去 40 年来，人们提出了多种方法来实现这一目标。它们中的大多数只能应用于多维核磁共振谱的间接维度，或者需要特殊的数据处理来产生解耦的一维质子谱。最近，引入了在采集过程中质子光谱的完全解耦；这不仅显着减少了记录这些光谱的实验时间，而且消除了对任何复杂处理方案的需要。在这里，我们对宽带质子解耦质子实验的技术和应用进行介绍和概述。
Broadband homonuclear decoupling of proton spectra, that is, the collapse of all multiplets into singlets, has the potential of boosting the resolution of H-1 NMR spectra. Several methods have been described in the last 40 years to achieve this goal. Most of them can only be applied in the indirect dimension of multi-dimensional NMR spectra or special data processing is necessary to yield decoupled 1D proton spectra. Recently, complete decoupling of proton spectra during acquisition has been introduced; this not only significantly reduced the experimental time to record these spectra, but also removed the need for any sophisticated processing schemes. Here we present an introduction and overview of the techniques and applications of broadband proton-decoupled proton experiments.
