Abstract
We introduce here a heteronuclear dipolar decoupling scheme in solid-state nuclear magnetic resonance that performs efficiently at the rotary resonance conditions, where otherwise dipolar couplings are re-introduced. Results are shown proving the efficiency of this scheme at two magnetic fields under magic-angle spinning frequencies of 30 and 20 kHz.
摘要
我们在这里介绍一种在固态核磁共振中有效的异核偶极解耦方案，该方案在旋转共振条件下有效地工作，否则偶极耦合将重新引入。结果表明，该方案在两个磁场下在 30 和 20 kHz 的魔角旋转频率下的效率。
