The aim of this paper is to provide a general picture of the spectral characteristics of some polycyclic aromatic hydrocarbon (PAH) derivatives. A great deal of data concerning PAHs has been reported in the literature, but there is lack of comprehensiveness about important parameters in the same experimental conditions for their nitro (NO(2)) and amino (NH(2)) derivatives such as absorption and emission characteristics. Thus, important parameters such as the molar extinction coefficient, absorption maxima, fluorescence maxima, and fluorescence quantum yield are reported here. The efficiencies of the reduction of NO(2)-PAHs to their corresponding amino compounds were also verified by means of high-performance liquid chromatography (HPLC). This class of derivatives represents one of the most toxic groups of carcinogenic substances and therefore the data reported here should be useful for toxicological research.
本文旨在全面呈现一些多环芳烃（PAH）衍生物的光谱特征。文献中已报道了大量关于多环芳烃的数据，但在相同实验条件下，其硝基（NO₂）和氨基（NH₂）衍生物的重要参数，如吸收和发射特性等，缺乏全面性。因此，本文报道了诸如摩尔消光系数、最大吸收波长、最大荧光波长和荧光量子产率等重要参数。还通过高效液相色谱法（HPLC）验证了将NO₂ - PAHs还原为其相应氨基化合物的效率。这类衍生物是最具毒性的致癌物质类别之一，因此本文所报道的数据应有助于毒理学研究。
