| 摘 要： | 本文提出了一个固态NMR体系中的组合180°脉冲Rx(180°),用于宽带布居数反转。在强射频场条件下,用平均哈密顿理论对Rx(180°)进行了计算。并且在计算机模拟和实验上证实了Rx(180°)比180°单脉冲的布居数反转效果要好。

| Abstract: | A Composite 180° pulse (Indicated by Rx(180)) for the population inversion in solid state NMR systems is presented. Under the strong rf field condition, Rx(180° composite pulse was calculated by use of Coherent Averaging Theory. That the performance of Rx(180° is superior to that of a conventional 180°single pulse is demonstrated by computer simulations and experimental results. |
