J分辨光谱学和许多其他实验中的一个主要问题是由于强耦合而出现的“伪像”。产生这些伪影的信号遵循与所需信号相同的相干传输路径，使得不可能使用相位循环或脉冲场梯度来抑制它们。我们提出了新的方法来抑制这些文物，适用于任何实验包含J-分辨脉冲序列元素，以及恒定时间的实验。© 2005 Elsevier Inc. All rights reserved.
A major problem in J-resolved spectroscopy and many other experiments is the appearance of "artefacts" due to strong coupling. The signals giving rise to these artefacts follow the same coherence transfer pathways as the required signals, making it impossible to suppress them using phase cycling or pulsed field gradients. We present new methods for suppressing these artefacts, applicable to any experiment containing a J-resolved pulse sequence element, as well as to constant-time experiments. © 2005 Elsevier Inc.
