Identifiers: Viologens. During the course of an investigation by ESR and polarographic techniques of the viologens, which are colored in reduced form, the spectrum of the biquaternary bipyridyl radical cation was obtained. Comparison of the experimental spectra with theoretical results indicates that the hyperfine splitting is the same for the 8 protons in the ortho and meta positions.
