摘要 提出了一种设计多量子相干激发脉冲序列的新方法,用双线旋转脉冲作为基本激发单元,按照自旋偶合网络构建脉冲序列,达到(一)满自旋数激发,P_(max)=N,(二)处于最佳转移条件下的高效率激发。 A new method of designing MQ excitation pulse-sequences with high efficiency and coherences of the highest order Pmax = N , where N is the total spin number, is proposed. According to the different spin coupling networks, the pulse sequences were designed by the bilinear rotation pulses as basic excitation elements. The relations between the pulse sequences and the spin coupling networks were established and can be applied to the simplification of complex spectra and confirmation of coupling networks.
