N2  - In an investigation into the coking mechanism of coal, polynuclear quinones have been adopted as models. The vibrational and electronic absorption spectra of indanthrone (I), 1,1?-dianthrimide (II), and 1,2,2',1'-anthraquinoneazine (III) are presented and discussed. The absorption spectra of I and II, together with other available evidence, favour the tetraketo form rather than the enol form as recently proposed by Wyman (1956) for structure I.
