摘要：

Dynamic polarization of protons of solutions containing nitroxide free radicals in low field was previously studied with the help of hypotheses justified here. It is shown that the formalism of populations is a good approximation of the more complicated formalism of the density matrix. These available results are used to calculate theoretically the shape of the nuclear signal when the electronic frequency of excitation is varied. The obtained line-shape shows a dissymmetry in good agreement with that of the experimental one when the coherent radiation of the protonic spins is eliminated.
