摘　　要：利用太赫兹(terahertz,THz)时域光谱技术室温下进行了蒽醌及其衍生物2_甲基蒽醌、蒽醌_2_磺酸钠、蒽醌_2,6_二磺酸钠、蒽醌_2,7_二磺酸钠在10～55cm-1(0.3～1.65THz)频谱范围内的光谱测量。结果表明,蒽醌及其衍生物在此波段有不同的吸收特征,它们的吸收可能是由于晶格振动引起的。THz时域光谱不仅能够鉴别分子结构存在微小差别的化合物而且还能鉴别同分异构体。The absorption spectra of anthraquinone, 2-methylanthraquinone, anthraquinone-2-sulfonic acid sodium salt, anthraquinone-2,6-disalfonic acid disodium salt and anthraquinone-2,7-disulfonic acid disodium salt have been measured by terahertz time-domain spectroscopy over the frequency range from 0.3 to 1.65THz at room temperature. It was found five compounds showed distinct fingerprint spectra in the THz region, which may be contributed to lattice vibrational modes. The result also suggests that Terahertz time-domain spectroscopy can identify not only compounds with similar chemical constituents but also isomeric compounds.
