中文摘要：

利用THz时域光谱技术测量了间甲基苯甲酸在0．2～1．8THz频率范围内的振动光谱，结合密度泛函理论计算的振动光谱，对观测到的强振动吸收峰进行了指认．比较不同的芳香化合物的振动光谱，间甲基苯甲酸分子的特征振动峰与其他芳香化合物的振动特征峰在0．2～1．8THz频率范围内明显不同．

英文摘要：

Low-energy vibrational modes of m-Toluic acid has been measured experimentally using terahertz time-domain spectroscopy in a frequency range of 0.2 to 1.8 THz at room temperature. Comparing with a DFT calculation, the observed strong absorption peaks have been attributed to different intramolecular vibrational modes. This study provides the character vibrational spectra of m-Toluic acid molecules in THz region for distinguishing between different aromatic compounds.
