| 摘 要： | 对π脉冲宽度的误差与频率偏置效应引起的TOSS谱的残余旋转边带进行了分析,证实了相位循环方法能够在一级近似下有效地抑制这种残余旋转边带。在比较宽的频率偏置范围内从实验上检验了相位循环方法的有效性。

| Abstract: | An analysis has been made on the residual sidebands in TOSS spectra caused by the errors in π pulse widths and the resonance offset effects, from which it can be concluded that phase cycling can efficiently suppress these residual sidebands to the first order. In a large range of resonance offsets, the efficiency of the phase cycling method has been tested experimentally. |
