Figure  2.  EPR  simulated  hyperine  patterns: A)  nitro  anion  radical  spectrum simulated in terms of one doublet accounting for one hydrogen  atom  (H-4)  and  two  triplets  assigned  to  two  nitrogen  atoms;  B)  nitro  anion radical spectrum simul
Table 1 summarizes the calculated and experimental  geometrical  data.  Noticeable  differences  were  found  on  the dihedral angle of the poly(oxo)methylenic dialkylamine  chain (see Figure 1)
