Chemical Sciences: A Manual for CSIR-UGC National Eligibility Test for Lectureship and JRF/Zero field NMR

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).
