✦ Synopsis

The correlation of the reactive component of the bimolecular quenching rate constant, k r , with DG for reactions of singlet molecular oxygen with phenols is interpreted in terms of classical and semiclassical theories of electron transfer. Both treatments indicate a diabatic process with a reorganization energy of about 0.46 eV. The observed diabaticity is in line with a crossing of states with different symmetry. Similar results were obtained for the reactions of singlet molecular oxygen with phenoxide ions in water.
