Magnetometer-Detected Nuclear Magnetic Resonance of Photochemically Hyperpolarized Molecules

, 2023
Photochemically induced dynamic nuclear polarization (photo-CIDNP) enables nuclear spin ordering by irradiating samples with light. Polarized spins are conventionally detected via high-field chemical-shift-resolved NMR (above 0.1 T).
