Resumen
Electron Spin Resonance spectra were obtained of the salicyliden-2-imino-5-nitropyrimidine (1(.-)), N,N-bis(5-nitro-salicyliden). ethylendiamine (2(.-)), 2-hydroxy-5-nitro-benziliden-5-iminoquinoline (3(.-)) anion I radicals produced by electro chemical reduction in DMSO. Hyperfine splitting constants were assigned by comparison with radical anions of similar structure and in some cases with the help of INDO method. For the (2(.-)) and (3(.-)) the substitutions in position meta affect greatly some proton coupling constants.
