Abstract By a flow technique chemically induced nuclear polarization is observed in the NMR-spectra of phenylhalides formed during photolysis of aroylperoxides in solution. The main features of the polarization are quantitatively explained by dynamic nuclear polarization (CIDNP) of protons in the intermediate phenyl radicals. Some details however indicate that a second polarization mechanism is also present. This mechanism leads to a multiplet-effect type polarization and operates presumably during bond fromation in the radical reactions. Some results on the magnetic field dependence of the nuclear polarizations are given.
