Zero field NMR

Zero field nuclear magnetic resonance (ZF-NMR) is a type of nuclear magnetic resonance spectroscopy that is conducted in the absence of a strong external magnetic field. Unlike traditional NMR, which relies on a strong, uniform magnetic field to align the nuclear spins of certain isotopes (usually hydrogen-1, carbon-13, or others), zero field NMR examines the behavior of nuclear spins in a near-zero magnetic environment.
