Abstract

The radical cation of 6-hydrodipyrido-[1,2-c:2′.1′-e]-imidazolium iodide (monomethylene diquat) has been investigated using ESR, ENDOR and triple resonance. The bridge methylene protons have a large hyperfine coupling constant (2.46 mT) and show second-order interaction both in the ESR and ENDOR spectra. The relative signs of the coupling constants were obtained using triple resonance. The observed ENDOR second-order splitting (0.009 mT) together with the line positions are in complete agreement with theoretical prediction.
