| 摘 要： | 讨论水溶液样品ＮＯＥＳＹ谱ω1维上出现的谐波，用辐射阻尼线形理论对实验进行了分析，证明了这些谐波是由辐射阻尼造成的伪信号．同时分析了这种伪信号在不同混合时间时的线形特征，与实验结果符合相当好，给出了实验上消除这种伪信号的方法

| Abstract: | Harmonic peaks appearing in ω1 dimension of the NOESY spectra on liquid water are sidcussed. The NOESY experiment is analuzed by using radiation damping line shape theory and the result shows that these harmonic peaks are artifacts induced by radiation damping. It is also shown that the line shapes of the artifacts are dependent on the mixing time,in good agreement with the experimental results. Some methods for eliminating these artifacts are proposed. |
