摘　　要：文章利用太赫兹时域光谱(THz-TDS)仪对香兰素在0.1-2.5THz波段的光谱特性进行了测量,并用Gaussian09软件对香兰素分子振动进行模拟。研究结果表明,香兰素在2.12THz的吸收峰是由O15-C16的摇摆振动引起的。为进一步研究香兰素提供了参考。The far-infrared absorption spectra of Vanillin has been measured by terahertz time-domain spectroscopy（THz-TDS） in the frequency range of 0.1-2.5THz at room temperature, And Gaussian09 software is applied to simulate the absorption peak of vibration mode of Vanillin molecule. The results show that the experimental results of vanillin in 2.12 THz absorption peak is caused by O15-C16 swing vibration. This provides a reference for further study of vanillin.
