Time-resolved polarized neutron scattering (dots) and NMR (boxes) from dynamic polarized protons of EHBA-Cr(V) in a deuterated solvent. The bis­(2-hy­droxy-2-ethyl­butyrato) oxochromate anion is surrounded by 20 hydrogens of its 4 ethyl groups (Krumpolc & Rocek, 1979View full citation). Their polarization gives rise to an impressive change of the neutron scattering intensity after each change of the direction of DNP. The direction of polarization was changed every 10 s. The delayed polarization of the remote protons of the deuterated solvent seen by NMR proceeds more slowly (after van den Brandt et al., 2002View full citation). The experiment was done at D22 at the ILL.
