✦ Synopsis

A new type of rotor-synchronized 'R/L-driven' polarization-transfer techniques is introduced and is shown to lead to efficient rare spin polarization transfer over a large range of chemical shifts. It is demonstrated that polarization transfer can proceed via a zero-or double-quantum mechanism depending on the design of the pulse sequence. It is shown experimentally that R/Ldriven polarization transfer can be observed not only in isotopically enriched compounds but also in natural abundance (e.g. 'V) samples.
