Spin-Orbit Coupling Induced Electron Spin Polarization: Influence of Heavy Atom Position

摘要

Echo-detected FT-EPR spectra have been observed for the quinone anion radical generated from the photoexcitation of duroquinone (DQ) in the presence of N. N-dimethylaniline (DMA) and its monohalogen substituents in 1-propanol. When DMA and 4-Cl DMA were used as the electron donor, the net-emissive polarization due to a triplet mechanism was observed.
