Triple Ions

Electron spin resonance spectroscopy has been used to study triple ions formed between pyrazine and tetramethylpyrazine and the cations Li+, Na+, K+ in dimethoxyethane, tetrahydrofuran, and 2-methyl-tetrahydrofuran. Differential line-broadening effects are reported within the hyperfine splitting patterns of the alkali metals incorporated into the triple ions, and a possible application of such effects to the study of ionic association is described.

Triple Ions

The formation, in tetrahydrofuran, of triple ions of the formula Na2Q+ (Q = p-benzosemiquinone, 2,3-, 2,5-, 2,6-dimethyl-p-benzosemiquinone, durosemiquinone) has been detected by electron spin resonance spectroscopy. The spectra show asymmetric broadening within the 23Na hyperfine multiplets. From the direction of this broadening, it is deduced that the sodium ions lie in the plane of the semiquinone anion, one sodium ion associating with each oxygen.
