Refocusing pulses: A strategy to improve efficiency of phase-modulated heteronuclear decoupling schemes in MAS solid-state NMR

摘要

Graphical abstractDisplay OmittedHighlights?The universality of using refocusing pulses to improve existing standard decoupling sequences is probed.?The success of this approach relies on judiciously choosing the phase of theπpulses.?Refocusingπ-pulse improves the offset tolerance and intensity compared to XiX.?Theπ-pulse modification is superior to the previous phase and amplitude modification of XiX.AbstractThe strategy of usingπpulses in conjunction with continuous-wave radio-frequency fields to refocus spin inte
