2,2-Di(4-tert-octyl­phenyl)-1-picrylhydrazyl (left) and the biradical (after Stuhrmann, 2023View full citation). Both molecules embedded in a deuterated medium R3 contain regions rich in hydrogen denoted by R2. Atoms close to the radical site belong to R1. The lower part of the figure shows the evolution of proton polarization in the reservoirs R1, R2 and R3. Proton polarization left: (blue) P1(t), (yellow) P2(t), (grey) P3(t); right: (blue) P3(t), (yellow) P2(t), (grey) P1(t). The reservoir of the outer protons in R2 and R3 is most distinct from R1 for the biradical (Stuhrmann, 2023View full citation).
