Abstract:

 The CIDEP of photolized р-benzosemiquinone and 2-hydroxy-2-propyl radicals was measured with time-resolved ESR spectrometer. The CIDEP of р-benzosemiquinone radical is belong to TM mechanism. The influence of microwave power and solution concentration on evoluation was investigated. The condition of spin polarization of 2 hydroxy-2-propyl radical, which is belong to RPM mechanism, was investigated.

Key words: CIDEP;Time-resolved ESR, Photolized p-benzosemiquinone radical, Photolized 2-hydroxy-2-propyl radical
