Small angle neutron scattering experiments have been performed on liquid crystalline 163 basepair NaDNA fragments in aqueous solution in the concentration range 190–285 mg ml. To induce a macroscopic alignment, a magnetic field was applied either parallel (B∥ configuration) or perpendicular (B⊊ configuration) to the incoming neutron beam. The isotropic scattering pattern in the B∥ configuration and the anisotropic scattering in the B⊊ configuration agree with the cholesteric structure of the liquid crystalline solutions. From the anisotropic scattering in the B⊊ configuration, information on the orientation ordering can be derived. For this purpose, the experimental data are compared to the form function of a uniform rod including a gaussian orientation distribution. The standard deviation of this distribution is approximately 20° for all concentrations investigated here.
