提出了一种相位循环方案，用于抑制自旋-1核的四极回波光谱中由于脉冲宽度有限而产生的光谱伪影。利用平均哈密顿理论和虚拟自旋-1算子的形式建立了相位循环方案。对氘化聚乙烯进行了仿真和实验，突出了有限脉冲宽度引入的光谱伪像，并成功地消除了所提出的相位循环方案。(c) 2006爱思唯尔公司版权所有。
A phase cycling scheme for suppressing spectral artifacts introduced in quadrupolar echo spectroscopy of spin-1 nuclei due to finite pulse width effects is presented. The phase cycling scheme is developed using the formalism of average Hamiltonian theory and fictitious spin-1 operators. A simulation and experiment on deuterated polyethelene is performed highlighting the spectral artifact introduced by finite pulse widths and successful removal with the proposed phase cycling scheme.
