Experimental and theoretical polarization yield considering S‐T0 mixing. The polarization was simulated assuming different initial spin orders at the onset of SOT (singlet‐triplet mixing without or with decoupling; Eq. 7 or 8). The mixing factor, λ, was set to 0.1. When a weighted sum (reflecting the fact that the spins evolve freely for two seconds and decoupling is applied only for three seconds), the polarization decreased to 8.2 %.
