✦ Synopsis

Transient alkyl radicals and triplet-state molecules are generated simultaneously in solution by laser flash irradiation, and chemically induced electron polarization (CIDEP) of the radicals is studied by time-resolved ESR spectroscopy. The presence of triplet-state molecules is found to induce emissive ESR polarizations. The phenomenon is attributed to triplet-state quenching by radicals as well as to quartet-doublet mixing and splitting in radical-triplet encounters.

In flash-photolysis experiments the phase of RPM polarization in the radicals commonly changes in time after the flash, the patterns observed at longer times being apparently inconsistent with observations on the same radical systems made using alternative experimental techniques.
