"Pure shift" methods can greatly improve the resolution of proton NMR spectra. However, current pure shift spectra show small periodic artefacts that prevent their use for studying dilute mixture components. A new technique, compatible with all current pure shift methods, is presented that suppresses such sidebands to arbitrary order, allowing ultraclean spectra to be obtained.
“纯位移”方法可以极大地提高质子核磁共振谱的分辨率。然而，目前的纯位移谱显示出小的周期性伪影，这妨碍了它们用于研究稀混合物成分。本文提出了一种与所有当前纯位移方法兼容的新技术，该技术可以将此类边带抑制到任意阶数，从而获得超纯净的谱图。
