This study introduces a conceptually new solvent suppression scheme with adiabatic inversion pulses for 1H-detected multidimensional solid-state NMR (SSNMR) of biomolecules and other systems, which is termed “Solvent suppression of Liquid signal with Adiabatic Pulse” (SLAP). 1H-detected 2D 13C/1H SSNMR data of uniformly 13C- and 15N-labeled GB1 sample using ultra-fast magic angle spinning at a spinning rate of 60 kHz demonstrated that the SLAP scheme showed up to 3.5-fold better solvent suppression performance over a traditional solvent-suppression scheme for SSNMR, MISSISSIPPI (Zhou and Rienstra, J Magn Reson 192:167–172, 2008) with 2/3 of the average RF power.

用于 1H 检测的固态 NMR 绝热反转的高效溶剂抑制

本研究为生物分子和其他系统的1 H 检测多维固态 NMR (SSNMR)引入了一种具有绝热反转脉冲的概念性新溶剂抑制方案,称为“绝热脉冲液体信号的溶剂抑制”(SLAP)。1 H-检测到的 2D 13 C/ 1 H SSNMR 数据在 60 kHz 的旋转速率下使用超快魔角旋转对均匀13 C-和15 N-标记的 GB1 样品进行检测,证明 SLAP 方案的性能提高了 3.5 倍SSNMR,密西西比州(Zhou and Rienstra, J Magn Reson 192:167–172, 2008)的传统溶剂抑制方案的溶剂抑制性能,平均射频功率为 2/3。
