Finite-pulse radio frequency driven recoupling with phase cycling for 2D 1H/1H correlation at ultrafast MAS frequencies
The first-order recoupling sequence radio frequency driven dipolar recoupling (RFDR) is
commonly used in single-quantum/single-quantum homonuclear correlation 2D experiments
under magic angle spinning (MAS) to determine homonuclear proximities. From previously
reported analysis of the use of XY-based super-cycling schemes to enhance the efficiency of
the finite-pulse-RFDR (fp-RFDR) pulse sequence, XY8 1 4 phase cycling was found to
provide the optimum performance for 2D correlation experiments on low-γ nuclei. In this …
