Benzosemiquinone

Though the relative orientations of methylimidazole and benzosemiquinone had little impact on the N δ nqi tensor, Fritscher found the hydrogen bond length to have a dramatic effect on η (Figure S9, Supporting Information ). 32 Shortening the N···O distance from 3.25 to 2.75 Å resulted in an increase in η from 0.17 to 0.61.
