Abstract :
Terahertz (THz) spectra of amino acids: glycine and L-alanine and these polypeptides are measured by THz spectroscopy. For both amino acids, the spectral features are more complicated with increasing the number of the chain length. This structural hierarchy is studied by DFT calculation results.
