title: Single-transition coherence transfer by adiabatic cross polarization in NMR.
abstract: Spin-state selective coherence transfer between single-transition coherences in a scalar-coupled two-spin system may be achieved by employing highly selective, constant amplitude radio frequency fields. We extend this method by employing amplitude-modulated pulses to achieve an adiabatic transfer, as shown in the picture (I=intensity). Different limiting cases are considered. The imperfect reversibility of the transfer reveals deviations from adiabaticity.
