A sensitivity enhancement method based on selective adiabatic inversion of a satellite transition has been employed in a (pi/2)CT-(pi)ST1-(pi/2)CT spectral editing sequence to both enhance and resolve multisite NMR spectra of quadrupolar nuclei. In addition to a total enhancement of 2.5 times for spin 3/2 nuclei, enhancements up to 2.0 times is reported for the edited sites in a mixture of rubidium salts.
一种基于卫星跃迁选择性绝热反转的灵敏度增强方法已应用于(π/2)CT-(π)ST1-(π/2)CT 光谱编辑序列中，以增强和解析四极核的多位点核磁共振谱。除了对自旋 3/2 核的总增强倍数达到 2.5 倍外，对于铷盐混合物中经编辑的位点，据报道增强倍数高达 2.0 倍。
