optically detected magnetic resonance zero-field optically detected magnetic resonance zf-ODMR ZF-ODMR A double resonance technique in which transitions between spin sublevels at zero applied magnetic field are detected by optical means (i.e. the polarisation or the intensity of light emitted or absorbed by the sample depends on the population distribution in the spin levels). Usually these are sublevels of a triplet and the transitions are induced by microwaves.
