To record a phase-sensitive 2D Clean TOCSY experiment with MLEV17, load the parameter set defined for the conventional phase-sensitive 2D TOCSY experiment using presaturation and change the pulse program to clmlevphpr. Modify acquisition parameters if required (d20 is the delay to allow compensation of NOE and ROE: in theory d20 = p6, in practice d20 = 2.6 * p6 ), and perform data acquisition and data processing as described.
