<jats:title>Abstract</jats:title> <jats:p>The weak absorption band (α-band) (εmax∼20) near 500 mμ of acenaphthenequinone was measured in various solvents. This band was determined as the n−π* transition band on the basis of the observed results on intensity and solvent effect. In dioxane, the n−π* transition bands of the o-quinones, including the α-band, largely shift towards shorter wavelengths. This fact, which is thought to be due to molecular complex formation, was discussed from the qualitative point of view. The relative height of the two main peaks of the α-band markedly depends upon solvents. The similar, though less marked, fact is seen in β-naphthoquinone. The two main peaks of the α-band were assumed to be due to the two n–π* transitions, whose transition energy difference is ca. 700 cm−1. It was found that the n–π* transition bands of the quinones, especially of p-benzoquinone, are markedly intensified in carbon disulfide. This fact is probably attributed to the large refractive index of this solvent.</jats:p>
