摘要

The chemically induced dynamic electron polariztiion (CIDEP) of the triplet molecule/triplet quencher/2,2,6,6-te tranethyl-1-piperidinyioxyl (TEMPO) systems were measured using the high time-resolved FESR spectrometer. The competi tion between the radical-triplet pair mechanism (RTPM) and triplet mechanism (TM) or radical pair mechanism (RPM) polarization in the solution of the triplet quencher was investi gated, and the relationship between reaction rate of the radi cal-triplet pair and quenching rate of triplet was deduced.
