中文摘要：为了研究2-甲基-5-硝基苯胺在太赫兹波段的光学特性，利用THz—TDS在室温氮气条件下测试2-甲基-5-硝基苯胺在0．2—3THz范围内的光学特性，得到了样品的太赫兹时域谱，经傅立叶转变得到频域光谱，同时获得了对应的吸收光谱。实验结果表明：2-甲基-5-硝基苯胺在此波段存在明显的特征吸收峰，可以作为特征光谱加以鉴别。此外，为了进一步解析其光谱吸收机理，运用密度泛函理论计算了在此频段的振动吸收谱，并对振动进行了归属。这项研究为偶氮染料中间体分子鉴别及更宽有效光谱区的实验测试研究提供了新的实验方法，也为服装偶氮染料检验提供了可能性。

外文摘要：In order to investigate the optical properties of 2 - Methyl - 5 - nitroaniline in the terahertz band, the paper attempts to study the optical properties of nitrogen 2 - Methyl - 5 - nitroaniline in the range of 0.2 - 3 THz by using THz - TDS under the conditions of room temperature and Nitrogen and then to get the frequency -domain spectrum by Fourier transformation, and also the corresponding absorption spectra. The experimental result shows that 2 - Methyl - 5 - nitroaniline has obvious characteristic absorption peaks which can be identified as a characteristic spectrum in this band. In addition, in order to further resolve its spectral absorption mechanism in this paper, the density functional theory is used to calculate the absorption spectrum in this band vibration. The study provided a new experimental method for the experimental test of the intermediate molecular identification of AZO dye and for widening effective spectral region and provided a new method for the identification of AZO dye test of imnorl and exhort clothes.
