Abstract
The effect of a magnetic field on the yield of products of recombination of triplet radical ion pairs in phototransfer of an electron between N,N-dimethylaniline and pyrene in ethylene glycol was investigated by laser strobe fluorometry. It was found that addition of a flexible-chain, linear polymer, polyacrylamide (PAAm), to the solution decreases the magnetic field effect (MFE) for concentrations higher than 130–140 g/liter. A linear correlation was established between the MFE and translational mobility of the reagents. A similar correlation was obtained for MFE in a viscous homogeneous liquid. A conclusion was drawn concerning the absence of a specific effect of PAAm on the cage effect based on the agreement of these correlations.
