aid to structural elucidation of these compounds the electronic spectra of a large number of substituted naphthoquinones were examined. The bands in the 240–600 mμ region of the electronic spectra of 1,4-naphthoquinone, juglone, and naphthazarin have been assigned to either benzenoid or quinoid electronic excitations and the effect of substitution on the position of these bands has been systematically
棘皮动物基于萘醌骨架精心构造了许多紧密相关的结构颜料(spinochromes)。为了阐明这些化合物,对大量取代的萘醌的电子光谱进行了研究。1,4-萘醌,ju酮和萘达沙林的电子光谱中240-600mμ范围内的谱带已被分配给苯类或醌型电子激发,并且已经系统地研究了取代对这些谱带位置的影响。结果,已经得出了许多经验相关性,这些经验相关性可用于未知颜料的结构确定。
