F-pair polarization and triplet mechanism (TM) polarization of durosemiquinone radical produced by light irradiation of duroquinone-phenol systems were discriminated at 260 K in a simple way based on the analysis of the enhancement factors in the steady-state method with intermittent light irradiation. Both polarizations are not so sensitive to viscosity or polarity of solvents. TM enhancement factor is nearly constant (−0.8) in wide range of viscosity (2.5–25 cP, 1 cP=0.001 Pa s). F-pair polarization is suppressed in some extent by halogenated solvents while TM polarization is not affected by such solvents.
