| Abstract: | In this paper,the terahertz （THz） spectra of five plant growth regulators are measured by using the THz time domain spectroscopy （THz-TDS）.Their refractive indexes and absorption coefficients in the THz frequency range are extracted.Utilizing the Guassian 03 software,the single molecule structures of the five samples are simulated and their resonance frequencies in the THz frequency range are calculated.The experimental and simulated results are in agreement with each other.This workdemonstrates the application possibility of the THz-TDS in analysis of agricultural chemicals residue. |
| Keywords: | terahertz plant growth regulators refractive index absorption coefficient |
