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 0.1 and 2.8 THz were obtained based on the physical model for extract-ing 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 demon-strate significantly potential to promote the research and application of biological materials in bio-chemical and medical fields by THz-TDS. 关键词：太赫时域光谱学氨基酸指纹光学参数
