摘要：

We present what is to our knowledge the first comprehensive far-infrared absorption measurement of flames. These measurements, covering the region of 7-88 wave numbers (0.2-2.65 THz) are only now made possible by the technique of terahertz time-domain spectroscopy. We observe a large number of absorption Lines-including those of water, CH, and NH3-in a stationary, premixed, propane-air flame. The absorption strength permits the determination of species concentration along the beam path. is determined by comparison of the relative strengths of the water vapor Lines.
