A double resonance technique in which transitions between spin sublevels are detected by optical means. Usually these are sublevels of a triplet and the transitions are induced by microwaves. For different types of optical detection the following expressions are used: ADMR
(delayed emission, non-specified), DFDMR
(delayed fluorescence), FDMR
(phosphorescence). If a reaction yield is followed the expression RYDMR
(reaction yield detected magnetic resonance) is used.
