Advancing homogeneous catalysis for parahydrogen-derived hyperpolarisation and its NMR applications.

Parahydrogen-induced polarisation (PHIP) is a nuclear spin hyperpolarisation technique employed to enhance NMR signals for a wide range of molecules. This is achieved by exploiting the chemical reactions of parahydrogen (para-H), the spin-0 isomer of H. These reactions break the molecular symmetry of para-H in a way that can produce dramatically enhanced NMR signals for reaction products, and are usually catalysed by a transition metal complex.
