Abstract
The INDO/S approach is used to study the structure/spectra relationshi p for some N,N'-disubstituted 1,4-diaminoanthraquinones. The calculate d intensity and position of the short-wavelength absorption band depen d on the molecular conformation, in agreement with the experimental da ta. The reflection spectra of crystalline 1,4-bisanilinoanthraquinone and 1,4-bis(mesitylamino) anthraquinone are reported and the crystal s tructure of the latter compound has been determined.
