Abstract
Time-domain electron-spin-resonance studies on p-benzoquinone using ethanol and isopropanol as solvents show emissively polarized ESR spectra of semiquinone and hydroxyalkyl radicals within 0·5 μs after the laser pulse at 248 nm. The hydrogen abstraction from the alcohols by the triplet excited quinone is concluded to be the primary photochemical step.
