In this work the terahertz spectra of benzene, toluene, p-xylene and styrene-four volatile organic compounds (VOCs) of interest in environmental pollution studies-have been measured in their liquid phase at room temperature using terahertz time-domain spectroscopy (THz-TDS). Their frequency-dependent refractive index and absorption coefficient have been extracted and analyzed in the spectral range from 0.2 to 2.5 THz. The optical properties of bi-component VOCs mixtures have also been investigated and described in terms of a linear combination of pure VOCs optical components.
在本研究中，利用太赫兹时域光谱（THz-TDS）在室温下测量了苯、甲苯、对二甲苯和苯乙烯这四种在环境污染研究中备受关注的挥发性有机化合物（VOCs）的液相太赫兹光谱。在0.2至2.5太赫兹的光谱范围内提取并分析了它们随频率变化的折射率和吸收系数。还研究了双组分VOCs混合物的光学性质，并根据纯VOCs光学组分的线性组合进行了描述。
