The chemically induced dynamic electron polarization (CIDEP) of the triplet molecule/triplet quencher/2, 2, 6, 6‐tetramethyl‐1‐piperidinyloxyl (TEMPO) systems were measured using the high time‐resolved ESR spectrometer. The competition between the radical‐triplet pair mechanism (RTPM) and triplet mechanism (TM) or radical pair mechanism (KIM) polarization in the solution of the triplet quencher was investigated, and the relationships between reaction rate of the radical‐triplet pair and quenching rate of triplet was deduced.
