This paper presents results of mm-wave spectral properties of chemicals in the 225-315 GHz frequency range at ambient atmospheric pressure. The effect of pressure broadening of the spectral lines is determined by both experiments and theoretical simulation. Subsequent to the laboratory measurements, the proof of the principle of the open-path monitoring of airborne chemicals was tested by using a monostatic swept-frequency radar system
