Organometallic Approaches to Optimization of Rhodium Catalysts for Efficient Parahydrogen-Induced Polarization

摘要

Hyperpolarization has been extensively investigated to overcome the intrinsic low sensitivity of nuclear magnetic resonance (NMR) spectroscopy by increasing population gaps between the Zeeman energy levels. Parahydrogen-induced polarization (PHIP)1 is an attractive hyperpolarization technique using parahydrogen, the spin isomer of molecular hydrogen with the antiparallel nuclear spins.
