Fig. 2

Polarization procedure including pH2 addition and SOT (a), the experimental cycle (b), and a diagram of the experimental setup (c). In (a), hydrogenation of a precursor molecule forms the 1H-hyperpolarized product (J-couplings between 1H and 13C nuclei indicated)65,68; subsequently, spin order is transferred to 1-13C via J-couplings and a pulse sequence (polarized nuclei are indicated in red). A more detailed presentation of the experimental procedure and setup (c) with technical drawings and photographs is given in the SI.
