PHIP (ParaHydrogen Induced Polarization
A special effect in NMR spectroscopy
PHIP: A powerful tool for the investigation of catalytic hydrogenations
- Strong enhancement of NMR signals
- Absorption and emission signal patterns caused by non-Boltzmann spin population
- Observation of intermediates of small concentrations
- Evidence for pairwise hydrogen transfer
- Determination of stereo- and regioselectivity
- Measurements of reaction kinetics
- Polarization transfer to hetero nucleids (13C, 31P, etc.)
