Homonuclear decoupling can give impressive improvements in spectral resolution when overlapping multiplet structures limit the interpretability of NMR spectra. General homodecoupling methods ("pure shift NMR") typically use either interferogram-style acquisition, which is slow but gives optimum resolution, or real-time acquisition, which is fast but gives broader lines. Here we describe an alternative data acquisition strategy that allows rapid acquisition without resolution loss, illustrating the method with band-selective homodecoupling experiments and demonstrating its advantages over competing methods.
当重叠的多重峰结构限制了核磁共振谱的可解释性时，同核去耦可以显著提高谱分辨率。一般的同核去耦方法（“纯位移核磁共振”）通常使用干涉图式采集，这种方法速度慢但分辨率最佳，或者使用实时采集，这种方法速度快但谱线较宽。在这里，我们描述了一种替代的数据采集策略，该策略允许在不损失分辨率的情况下快速采集，通过带选择性同核去耦实验说明该方法，并证明其相对于其他竞争方法的优势。
