A theoretical model of the solid-state 15N NMR spectrum in an isotropic 15N2O/1-proponal/trityl-radical mixture is presented, which makes it possible to calculate in-situ 15N polarization directly from the powder-spectrum shape of the measured 15N NMR peaks. The model is in excellent agreement with the experimental line shape. The maximum 15N polarization was calculated to be (114)%.
