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.
