Substantial (31)P NMR signal enhancement of more than two orders of magnitude at 7 T for free and bound PPh3 species was observed under reversible interaction of (PPh3)3Ir(H2)Cl with parahydrogen. The large improvement in sensitivity made single-shot (31)P NMR imaging of a model object possible. The observed effects are temperature and magnetic field dependent as shown experimentally and theoretically.
