Abstract Terahertz time-domain spectroscopy is a new coherent spectral technique based on femtosecond laser technology. The radiation band belongs to far infrared. This paper presents the absorption spectra of carbon monoxide measured by terahertz time-domain spectroscopy in the frequency range between 0.2 and 2.5 THz. The experimental results indicate that the carbon monoxide has many distinct characteristic spectra between 0.2 and 2.5 THz which agree with the calculated results. The absorption peaks become sharper with decreasing the pressure. This work establishes the basic spectra data for the future identification and characterization of carbon monoxide, and it is very significative to measure the harmful substance in the atmosphere by terahertz technology.
