| 摘 要： | The optical characteristics of four kinds of amino acids （tyrosine, arginine, histidine and glutamine） filled with nitrogen at room temperature were studied by THz time-domain spectroscopy （THz-TDS）. Well-resolved absorption and refractive spectrums between 0.I and 2.8 THz were obtained based on the physical model for extracting the optical parameters of materials in THz range. The results not only fill up the spectra gap of amino acids in far-infrared range, supply data for amino acid molecular identification and conformation analysis, but also demonstrate significantly potential to promote the research and application of biological materials in bio-chemical and medical fields by THz-TDS.
