Short summary
The RFDR sequence has been widely used for homonuclear recoupling. The paper describes a heteronuclear version of RFDR. HET-RFDR sequence transfers longitudinal polarization between heteronuclear pairs by applying RFDR on two channels simultaneously. We perform an operator analysis of HET-RFDR and RFDR. Such an analysis allows for better understanding of the influence of offsets and paths of magnetization transfers for both these experiments, as well as the crucial role of XY phase cycling.
