The fast static dipolar dephasing of the single-quantum 13C coherences is removed by multiple-pulse heteronuclear decoupling. The resulting slow dephasing of the 13 coherences allows for inserting appropriate gradient pulses into the pulse sequence. The presence of the large magnetic field gradient reduces the efficiency of the decoupling sequences which is compensated for by introducing a scheme of sequential slice selection across the sample.
