使用连续波电子太赫兹光谱仪在 220–330 GHz 频带内表征重要挥发性有机化合物的旋转吸收光谱。在受控压力下测量多种纯挥发性有机化合物的吸收光谱，吸收线频率与 JPL 分子光谱数据库一致，误差范围在 30 MHz 以内。这里介绍的工作是通过使用标准硅制造技术小型化来减小气体光谱系统尺寸的一步，这将使此类系统能够用于各种工业、环境和医疗传感应用领域。
The rotational absorption spectra of important volatile organic compounds are characterized in the 220–330 GHz frequency band using a continuous-wave electronic THz spectrometer. Absorption spectra of a variety of pure volatile organic compounds are measured at controlled pressures, and the frequencies of the absorption lines agree with JPL's molecular spectroscopy database to within 30 MHz. The work presented here is a step towards size reduction of gas spectroscopy systems through miniaturization using standard silicon fabrication techniques, which would allow such systems to be used in the field for various industrial, environmental, and medical sensing applications.
