%X Dynamic nuclear spin polarization (DNP) is mediated by the dipolar interaction of paramagnetic centres with nuclear spins. This process is most likely to occur near paramagnetic centres at an angle close to 45° with respect to the direction of the external magnetic field. The resulting distribution of polarized nuclear spins leads to an anisotropy of the polarized neutron scattering pattern, even with randomly oriented radical molecules. The corresponding cross section of,polarized coherent neutron scattering in terms of a multipole expansion is,derived for radical molecules in solution. An application using data of timeresolved polarized neutron scattering from an organic chromium(V) molecule is tested.
