zero-field nuclear magnetic resonance spectroscopy

synonym: zero-field NMR
https://doi.org/10.1351/goldbook.08442
Measurement method of nuclear magnetic resonance spectroscopy in which nuclear magnetic resonance spectra are acquired in an environment carefully screened from magnetic fields, including from the Earth’s field allowing the direct detection of J-spectra in the absence of Zeeman interactions (see Zeeman levels).
