Photolysis of acetone in the presence of various hydrogen donors and of 3-hydroxy-3-methyl-2-butanone involves the formation of propan-2-olyl radicals which show both electron and nuclear spin polarization. The electron polarization of the radicals leads to additional nuclear polarization of the reaction products. Transfer of electron to nuclear polarization can occur by cross-relaxation and cross-correlation. The latter is described in detail. Experimentally, the mechanisms lead to formation of net nuclear polarization for symmetrical radical pairs as well as an unusual kinetic behavior of multiplet effects.
