EFFECTS OF TX-100 MICELLES ON THE CIDEP MECHANISM FOR CREATING P-BENZOSEMIQUINONE RADICALS

A comparative study of the chemically induced dynamic electron polariz ation (CIDEP) spectra has been made experimentally with the time resol ved ESR spectrometer for the photolyzed p-benzosemiquinone radicals (P BQH(.)) 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; thu s the influence of micelle microenviroment on transient behavior of ra dicals is shown. The polarization transference mechanism is discussed to explain these experimental results.
