摘要：

Chemically induced dynamic electron spin polarization generated through the interaction between the excited singlet and triplet molecules with nitroxide radicals is measured in several solvents and micellar solutions. The relative intensity of net polarization is more enhanced than hyperfine-dependent polarization in highly viscous solvents and micellar solutions. The enhancement of net polarization is interpreted by the mixing of \Q-3/2) and \D1/2) states in the radical-triplet pair mechanism (RTPM) due to the slack motion of radical-triplet pairs. These results verify that net and multiplet polarizations are independently generated in RTPM.
