Abstract
The magnetic field dependence of geminate radical pair recombination following the photolysis of adenosylcob-(III)alamin (AdoCbl III ) has been studied by continuous-wave photolysis and picosecond laser flash photolysis technique. The net quantum yield (O) for continuous-wave 514-nm photolysis of AdoCbl III is decreased 2-fold at 80 mT in aqueous 75% glycerol and 1.8-fold at 50 mT in aqueous 20% Ficoll-400. No magnetic field dependence is observed in H 2 O. Glycerol is a microviscosigen that enhance geminate radical pair recombination by decreasing diffusion, whereas Ficoll-400 is a macroviscosigen that enhances geminate radical pair recombination by forming «cage» structure in solution
