a) Molecular diagram of parahydrogen (p-H2) addition to propylene over Rh/TiO2 at 0.05 T resulting in the formation of pseudo-singlet long-lived spin states (LLSS) of propane, followed by the application of the spin-lock induced crossing (SLIC) sequence to transform LLSS into observable magnetization and to detect the NMR signal. b) Schematic diagram of the experimental setup employed to perform p-H2 addition to propylene and to detect LLSS of propane produced at 0.05 T using the SLIC sequence. Note that separate 1H/1H Rx and Tx coils were used, with the internal solenoid (Rx) geometrically decoupled from the outer saddle-shaped coil (Tx) by orienting them orthogonally (in addition to mutual orthogonality of B1 fields of each RF coil to the main B0 field, see SI).
