Parameters and simulated polarization yield. The polarization level for SUC was determined for Goldman's sequence and PH‐INEPT+ (Figure 1) depending on the state of the spin system after hydrogenation and before the SOT. Either a pure (with decoupling) or time‐averaged singlet state (without heteronuclear decoupling during hydrogenation) was assumed. The total duration of SOT (t_SOT) is the sum of all the free evolution intervals. For the SOTs, on‐resonant pulses, ideal flip angles were used and relaxation was neglected.
