ABSTRACT
A comparative study of the chemically induced dynamic electron polarization (CIDEP)spectra has been made experimentally with the time resolved ESR spectrometer for the photolyzed p-benzosemiquinone radicals (PBQH)in ethylene glycol and Triton X-100 (TX-100)micelle solutions.The polarization of PBQH'is mainly the triplet mechanism (TM) of origin and at times also is involves some radical pair mechanism (RPM)in TX-100 micelle solution, the effect of RPM increases, but there is not the same effect in homogeneous ethylene glycol (EG) solution; thus the influence of micelle microenviroment on transient behavior of radicals is shown. The polarization transference mechanism is discussed to explain these experimental results.
