摘要：

Absorptive CIDEP signals of nitroxide radical were first observed in fluoranthene-TEMPO, coronene-TEMPO, pyrene-TEMPO, and naphthalene-TEMPO systems by time-resolved ESR. The absorptive spin polarization was interpreted by RTPM with doublet precursor of the radical triplet pair. From the CIDEP decay profiles and triplet quenching experiments, it was concluded that the generated CIDEP in these systems is explainable by the simultaneous operation of both doublet and quartet precursor RTPMs.
