Zero field NMR is the NMR spectrum analysis of certain substances in an environment carefully screened from magnetic fields. It is useful for studying nuclei with spins greater than 1/2, and for studying molecular dynamics.
It is "commonly but inaccurately known as nuclear quadrupole resonance" (NQR).
