Spectrum characteristics of nitrofen by terahertz time- domain spectroscopy

摘要：

This paper firstly presents the preliminary research on nitrofen with terahertz time-domain spectroscopy (THz-TDS). Different weight ratios of nitrofen in nitrofen-polyethylene combinations were measured. We employed linear fit between not only absorption coefficient but also average refractive index and the concentration of nitrofen. In the frequency region from 0.4 THz to 2.2 THz, seven characteristic absorption peaks of pure sample had been observed, four of which were assigned by using density function theory. Our study demonstrates that THz-TDS is an effective tool to distinguish nitrofen.
