We measured the absorption spectra of chiral compounds of D,L,DL-tyrosine and D,L,DL-tryptophan by terahertz time-domain spectroscopy over the frequency range from 0. 1 THz to 2. 0 THz at room temperature. We found six amino acids showed distinct fingerprint spectra in the THz region. Our result also suggests that we can identify the enantiomers and their racemic compounds by measuring the absorption spectra in the THz region
Key words： terahertz time2domain spectroscopy; enantiomers; amino acid
